Cave of Gems series: two risk models inside one cave
Within gem-themed adventure slots, Cave of Gems occupies BF games' compact risk-comparison lane: the same 5x3, 30-payline frame supports either a high-volatility bonus-buy game or a medium-volatility sequel built around feature choice. Shared bet limits of 0.3 to 90 make the mechanical differences easier to isolate.

Cave of Gems, released in 2024, sets the higher-risk baseline with a 94.09% RTP, 500x maximum win and bonus buy. Multipliers, extra free spins and free-spin multipliers place most of the variation inside the bonus, while the bomb imagery reinforces the cave-exploration theme.
Cave Of Gems Dice shifts the formula in 2025 to medium volatility, a 96.08% RTP and a 750x maximum win. Bonus buy gives way to sticky wilds, energy collection and a choice of free-spin modes. The sequel raises the stated ceiling while handing the player more control over the bonus route, rather than simply making the original more volatile.
