Bonus functions and unique mechanics
- Wild-symbol: depicted as a flashlight. Replaces all regular symbols for creating winning combinations.
- Scatter-symbol: game logo. Does not trigger free spins, but can pay out prizes for 3+ on the screen.
- Heist Mode: activates when 3 or more detective symbols drop. The player receives 20 free spins, during which special diamond symbols are added to the reels.
- Diamond Heist Respins (Hold & Win): this key mechanic activates when 5 or more diamond symbols appear on the screen (including Mini, Major, Mega, and cash). All diamonds are fixed, and the player receives 3 initial spins. Each new diamond that lands on the reels resets the spin counter back to 3. The goal is to fill the entire field to win the Mega Jackpot worth 500x the bet. Mini (100x) and Major (250x) jackpots are also available.
- Random modifiers: during bonus rounds, various modifiers can be activated, such as adding Wild symbols or multipliers, which increase the winning potential.
Expert opinions and recommendations
Diamond Heist Hold & Win — this is a balanced slot that offers both small regular wins in the base game and significant potential in bonus modes.
To maximize the win, the game recommends
Play with the maximum bet if the bankroll allows, as the size of jackpots in the Hold & Win mode directly depends on your bet. Be prepared for periods of waiting, characteristic of medium-high volatility, but do not lose patience — the main prizes are hidden in the bonus functions.
Mathematical model
- The slot has a standard RTP of 96.0% for the market and medium-high volatility. This means that wins will occur regularly, but large payouts are rare and require activation of bonus functions.
- The hit frequency is around 26.5%, and the Heist Mode is triggered on average once in 216 spins.
Compared to analogs
- Gates of Olympus (Pragmatic Play): has similar volatility and theme of wealth, but uses cascading payouts instead of Hold & Win.
- Bonanza Megaways (Big Time Gaming): offers significantly larger winning potential (up to 21,000x), but has a much higher volatility.
