15 Coins supplies the foundation with a 5x3 screen, Hold and Spin, Mystery Drop, cash collection and volatility settings spanning low, medium and high. Its 1,000x maximum makes the adjustable risk profile more important than the payout ceiling. 15 Coins Grand Gold Edition preserves Variable Volatility but adds a multi-level bonus and doubles the maximum to 2,000x.
The Platinum and Diamond releases turn the line into a more conventional high-ceiling progression. 15 Coins: Grand Platinum Edition formalizes a 15-payline frame, adds fixed jackpots and reaches 2,500x. 15 Coins Grand Diamond Edition keeps 15 paylines but raises the maximum to 5,000x through a mix that includes cash collection, additive symbols and sticky symbols. Choose the original or Gold for adjustable volatility; choose Platinum or Diamond when a fixed, sharper reward profile matters more.
