Hold and Spin Slot Machine Strategy
Hold and Spin games like Lock It Link and Dragon Link are some of the most profitable machines for advantage players. Locked symbols create visible, persistent state that skilled players can turn into a genuine edge. This guide covers the mechanics, the scouting process, and exactly how to play these machines for maximum EV.
Under the hood
How Hold and Spin Works
Hold and Spin is a bonus mechanic where landing a qualifying number of money symbols on a single spin triggers a locked-reel respin feature. The standard trigger is 6 money symbols on a 5x3 grid. Once triggered, each money symbol locks in place and you receive 3 respins. On every subsequent respin, if a new money symbol lands anywhere on the reels, it locks to that position and the respin counter resets back to 3.
The feature ends in one of two ways. If the respin counter runs down to zero without a new symbol landing, the feature concludes and you collect the combined value of all locked symbols. If every position on the reel set fills with locked money symbols — all 15 positions on a 5x3 grid — you are awarded the Grand jackpot in addition to the full symbol total.
The accumulated value on the reels is visible at all times. This is the core mechanic that makes Hold and Spin machines attractive to advantage players: state is not hidden. When a player walks away from a machine mid-feature or with symbols locked, any player who sits down can see exactly what has been accumulated.
Why Hold and Spin Is a Goldmine for AP
Most slot machine value is invisible. You cannot see RTP cycles, you cannot see how close a base game is to a feature. Hold and Spin machines break this rule because locked symbols are literally displayed on the screen. A machine with 4 locked money symbols sitting unprompted is broadcasting its state to everyone who walks by.
This visible accumulated state creates a classic advantage play scenario. If a casual player triggers the Hold and Spin bonus, collects a few locked symbols, then abandons the machine mid-feature because they ran out of credits or got distracted, an AP player who sits down immediately inherits all of that accumulated value. The remaining respins and locked symbols are theirs to collect at the cost of a single spin.
Even outside of mid-feature abandonment, scouting Hold and Spin machines is valuable because you can identify machines where a player has built up significant locked symbol counts and the bonus is close to triggering. With 200+ machine guides covering trigger thresholds, our database tells you exactly when a particular Hold and Spin variant crosses into profitable territory.
Mid-feature abandonment plays
A player triggers Hold and Spin, locks 8 symbols, runs out of credits, and walks away. The feature is still active on screen. You sit down, insert credits, and complete the feature — collecting all 8 accumulated symbols plus any additional ones that land. This is the highest-value Hold and Spin AP scenario.
Near-trigger scouting
Even without an active feature, machines close to the trigger threshold have elevated EV. If you know a Lock It Link variant triggers at 6 symbols and a machine has clearly been heavily played, the base game RNG will eventually produce a trigger — and your investment in reaching it may be below the expected feature value.
Linked jackpot elevation
Dragon Link and similar games share jackpot tiers across a bank of machines. When a bank's Mini, Minor, Major, or Grand jackpots are elevated above reset — visible on the display above the machine bank — every machine in that bank has increased EV, not just machines with locked symbols.

Scouting Hold and Spin Machines
Effective scouting for Hold and Spin machines means knowing what to look for before you set foot on the casino floor. The process is fast once you have a system. See our accumulator state strategy guide for the broader framework this fits into.
Scouting Checklist
- Check for active features first. As you walk past any Hold and Spin machine, glance at the screen. An active Hold and Spin feature is immediately visible — the reels freeze, symbols lock, and the respin counter appears. An active feature on an unoccupied machine is the highest-priority find on any scouting walk.
- Look for locked symbols between sessions. Some machines display locked symbol positions or accumulated state even between active play sessions. This is game-specific but worth checking. Dragon Link machines in particular sometimes display residual information from the prior session.
- Check the jackpot display above linked banks. Hold and Spin machines with linked jackpots display current jackpot values on a shared display above the machine bank. Compare current values to typical reset values. Our machine guides list the reset values for the Hold and Spin titles we cover, such as Cash Falls and Piggy Bankin' — we publish no guide for Lock It Link or Dragon Link.
- Note bonus trigger proximity. If a machine is actively being played and you observe money symbols appearing frequently in the base game, it may be approaching a trigger. Watching a few base game spins to assess symbol frequency can help you decide whether the machine is worth waiting for.
- Check all denominations in the bank. Most Hold and Spin games are available in multiple denominations. A penny denomination machine may show no AP value while the quarter machine in the same bank has accumulated significant jackpot elevation. Always check all denominations before moving on.
Popular Hold and Spin Machines and Their Trigger Thresholds
Each Hold and Spin game has its own configuration, trigger threshold, and jackpot structure. Understanding the differences between titles lets you prioritize which machines to scout and set accurate EV expectations. See our link-style slot machines strategy guide for additional context on how these games are structured.
Lock It Link (Aristocrat)
Lock It Link is available in Night Life, High Stakes, Diamonds, and Sahara Gold variants. The standard trigger is 6 money symbols on a 5x3 grid. Lock It Link features a fixed Grand jackpot that scales with denomination, with smaller fixed Mini and Minor jackpots that still add up when the feature stacks multiple locked symbols. We publish no Lock It Link guide, so read the values off the cabinet rather than trusting a remembered figure.
Dragon Link (Aristocrat)
Dragon Link — Palace of Riches, Golden Century, Happy and Prosperous, Spring Festival — shares jackpots across a linked bank of machines. The display above the bank shows all four tiers. Dragon Link triggers on 6 money symbols but the linked jackpot structure means elevated bank jackpots increase EV on every machine in the bank simultaneously. Dragon Link is one of the most valuable AP targets when a bank jackpot is well above reset.
Cash Falls (IGT)
Cash Falls uses a different grid configuration than Aristocrat titles and triggers Hold and Spin at varying symbol counts depending on the specific variant and denomination. Cash Falls machines display the accumulated coin value directly during the base game in some variants, giving scouting AP players clearer state visibility than competing titles. Check our machine guide for the specific trigger count for the Cash Falls variant in your casino.
Piggy Bankin (WMS)
Piggy Bankin is one of the original Hold and Spin style games. The mechanic is slightly different — a piggy bank symbol fills during base play and breaks when a qualifying spin occurs, awarding the accumulated coins. Because the fill level of the piggy bank is visible, AP players can assess state at a glance. Piggy Bankin machines are less common on modern casino floors but still appear at many regional casinos.
Bankroll
Bankroll Requirements for Hold and Spin Sessions
Hold and Spin machines are high-variance by design. The feature itself is rare, and even when you trigger it, outcomes range from a few symbol values to the full Grand jackpot. This variance requires a larger bankroll buffer than lower-volatility AP plays. See our slot machine bankroll management guide for the full framework.
The standard bankroll recommendation for Hold and Spin AP sessions is a minimum of 300 max bets for the denomination you are targeting. At a penny denomination machine playing max bet of $2.50, that means a $750 session bankroll. At a quarter denomination machine with a $5.00 max bet, you need $1,500. This buffer accounts for the variance in reaching the bonus trigger even when starting from an elevated state.
Bankroll Principles
- Mid-feature abandonment plays require minimal bankroll. If you find an active Hold and Spin feature on an unoccupied machine, the bankroll requirement collapses. You only need enough credits to complete the remaining respins — often a single spin. This is why mid-feature abandonment plays have the highest risk-adjusted EV of any Hold and Spin AP scenario.
- Near-trigger scouting plays require 300+ max bet buffers. When playing toward a trigger from an elevated but not-yet-triggered state, variance is high. Even a machine at 80% toward its EV breakpoint can take 200+ spins to trigger. Plan your bankroll for the worst-case scenario, not the average.
- Never play through a feature at a denomination above your buffer. If a dollar denomination Dragon Link machine shows elevated jackpots but your session bankroll is $500, you do not have adequate buffer for a 300 max-bet float. Play the penny or nickel denomination in the same bank instead — the jackpot elevation applies to all denominations on linked banks.
- Check the machine guide to verify before sitting down. A hold-and-spin bonus has no must-hit-by ceiling to compute against, so the qualifying state comes from the machine's own Run the Slots guide rather than from the must-hit-by calculator. Check it before committing bankroll.
Exit Strategy — When to Leave a Hold and Spin Machine Mid-Session
One of the most common errors AP players make on Hold and Spin machines is staying too long past the point where the play is still profitable. Having a clear exit framework before you sit down prevents emotional decision-making from eroding your edge.
- Set a hard stop based on bankroll depletion. Decide before sitting down how many max bets you are willing to invest. If you reach that number without triggering the feature, leave. Do not rebuy to chase — the machine's EV may still be positive, but your session bankroll management takes priority.
- Leave immediately after a disappointing feature result. If you trigger Hold and Spin but collect a below-average result (few locked symbols, no jackpot tiers hit), the machine has reset to neutral state. There is no elevated probability of a better result on the next bonus. Move on.
- Leave if linked jackpots reset during your session. On Dragon Link and similar games, if another player on the linked bank hits the Major or Grand jackpot while you are playing, the jackpot tiers reset. The AP justification for that denomination may disappear instantly. Recalculate EV before continuing.
- Never leave an active feature without your ticket. If you need to step away, cash out first. An active Hold and Spin feature on an unoccupied machine will be claimed by the next AP player who walks past — and rightfully so, because that is the game.
- Revisit the Must-Hit-By calculator after a large jackpot hit. A Grand jackpot win is a windfall, but it also resets the machine entirely. After collecting, recalculate from the new reset state. The machine is likely -EV at that point. Leave and scout for the next opportunity.

Common questions
Frequently Asked Questions
What is Hold and Spin in slot machines?
Hold and Spin is a bonus mechanic found in games like Lock It Link, Dragon Link, Cash Falls, and Piggy Bankin. When you land a qualifying number of money symbols (typically 6 or more on a 5x3 grid), those symbols lock in place and you are awarded 3 respins. Each time a new money symbol lands during the respins, it locks and the count resets to 3. The feature ends when you either exhaust the respins or fill the entire reel set, which awards the Grand jackpot.
Is Lock It Link an advantage play machine?
Yes. Lock It Link qualifies as an advantage play machine because it accumulates visible state. Money symbols that land during the bonus lock to the machine. Between sessions, locked symbols can persist on screen if a player abandons the machine mid-feature, or the bonus can be approaching trigger threshold with the reel positions visible to a scouting AP player. The key is knowing the trigger threshold for the specific variant — Night Life, High Stakes, Diamonds, and Sahara Gold all have different configurations covered in our machine guides.
How many money symbols do you need in Hold and Spin?
The standard trigger threshold is 6 money symbols landing simultaneously on the base game reels. However, this varies by game. Lock It Link Night Life triggers at 6 on a 5x3 grid. Some Cash Falls variants trigger at 6 to 8 symbols. Always check the specific game's pay table, and where we cover the machine, the Run the Slots guide for the exact threshold. The trigger count directly determines the EV of an AP approach — lower triggers are generally more favorable because the feature starts with more symbols already locked.
What is the Grand Jackpot in Hold and Spin?
The Grand Jackpot is awarded when all positions on the reel set are filled with locked money symbols during the Hold and Spin feature. On a standard 5x3 grid that means all 15 positions locked. The Grand is typically a fixed jackpot — not a progressive — ranging from a few hundred dollars to several thousand depending on the machine denomination and game title. Because filling the entire grid is rare, the Grand is heavily weighted toward higher denominations to justify the difficulty.
Can you tell when a Hold and Spin machine will bonus?
Not with certainty — Hold and Spin triggers are determined by a certified random number generator. However, AP players focus on visible state clues rather than predicting random outcomes. If you arrive at a machine and see money symbols locked on screen from an abandoned feature, that is remaining value you can claim by inserting credits and continuing the session. Additionally, knowing trigger thresholds lets you calculate whether the current state is above the EV breakeven point for the denomination being played.
Is Dragon Link Hold and Spin worth playing AP?
Dragon Link can be worth playing for advantage play, but it requires careful evaluation. Dragon Link features multiple jackpot tiers — Mini, Minor, Major, and Grand — with a prominent display above the machine. The key AP angle is when a player abandons the machine with locked symbols still on the reels, or when the progressive jackpot tiers on a linked bank have been elevated significantly above their reset values. Dragon Link is not one of the 200+ titles we publish a guide for, so the read here is the one you can make yourself: locked symbols left on the reels, and tier values well above their resets.
