Diamonds & Devils / Jade Monkey Slot Strategy
Diamonds & Devils and Jade Monkey Deluxe by Light & Wonder feature persistent prizes above each reel collected via diamonds. Learn when diamond count and credit values combine for a genuine +EV play.
What Are Diamonds & Devils and Jade Monkey?
Diamonds & Devils Deluxe and Jade Monkey Deluxe are companion accumulator slot machines by Light & Wonder. Both share the same mechanic: persistent prize values sit above each reel, and players collect diamond symbols to unlock those prizes. A devil or monkey symbol can remove progress on a specific reel.
The AP classification is accumulator. Reel progress and diamond counts persist between players, creating opportunities when a previous player has built up collections near trigger thresholds.
How the Accumulator Mechanic Works
- Persistent prizes: Each reel has a prize value displayed above it. Collecting diamonds brings the player closer to winning that prize.
- Reel difficulty varies: Reels one and two are easier to trigger; reel five is harder. Apply looser thresholds to the first two reels and tighter thresholds to reel five.
- Devil / monkey risk: Landing a devil (Diamonds & Devils) or monkey (Jade Monkey) symbol can wipe progress on a reel. This downside is factored into the trigger thresholds.
- Free games meter: Separate from reel prizes, a free games meter accumulates. The trigger thresholds for free games depend on your current diamond count and the meter value.
Key Insight
Diamond count is a multiplier on the value of pending prizes. Two diamonds dramatically lowers the threshold for a +EV play. A machine with two diamonds already collected on reels one or two can be worth playing at credit values that would be insufficient on reel five or with zero diamonds.
Identifying +EV State
Play Triggers
- 8 free games showing with two diamonds collected
- 16 free games showing with one diamond collected
- 24 or more free games — always play regardless of diamond count
- Credit values worth at least 10x your bet above the reels with two diamonds collected
- Note: reels one and two qualify at slightly lower thresholds; reel five requires tighter conditions
Play / Walk Rules
- Play: Any trigger condition above is met — free games count exceeds threshold for current diamond count, or credit values are 10x+ bet with two diamonds.
- Walk: No trigger condition is met. Do not play on partial progress without meeting the thresholds.
- Reel difficulty matters: Apply the thresholds more generously to reels one and two, more conservatively to reel five.
- Stop after the trigger fires: After a prize or free games event resolves, re-evaluate from scratch before continuing.

Frequently Asked Questions
What are Diamonds & Devils and Jade Monkey?
Diamonds & Devils Deluxe and Jade Monkey Deluxe are companion slot machines by Light & Wonder sharing the same mechanic. Persistent prizes sit above each reel. Players collect diamonds to win prizes, but a devil or monkey symbol can remove accumulated progress.
How does reel difficulty differ in these games?
Reels one and two are easier to trigger than reel five, which is more difficult. This means you can apply slightly looser thresholds on the first two reels while reel five requires tighter conditions before a play is justified.
What are the free games triggers for Diamonds & Devils?
The free games triggers depend on diamond count: 8 free games with two diamonds, 16 free games with one diamond, and 24 or more free games always qualifies as a play even with no diamonds.
When do credit values create a play trigger?
Credit prize values worth at least 10x your bet combined with two diamonds create a play trigger. The credit value displayed above each reel represents the potential prize — evaluate this in combination with your diamond count.
What is the devil or monkey symbol risk?
A devil symbol (Diamonds & Devils) or monkey symbol (Jade Monkey) can remove collected progress on a reel, resetting the diamond count. This risk is already factored into the trigger thresholds — only play when the stated conditions are met, which account for this downside.
