Gameplay structure and mechanics
The base game is intentionally simple, with limited win frequency and modest payouts. This design keeps attention on triggering the Hold & Win bonus, which defines the slot’s overall performance.
Wild symbols help support base-game combinations, but they are not the main source of larger wins.
Core gameplay elements
- 27 all-ways wins on a compact 3×3 grid
- Wild symbols supporting base-game wins
- Hold & Win feature with locked symbols
- Bonus jackpots available during feature rounds
- Optional Buy Bonus for direct access
Hold & Win bonus and jackpots
The Hold & Win feature activates when the required number of bonus symbols appears during regular spins. Once triggered, all bonus symbols lock in place and a respin counter starts.
Each new bonus symbol resets the respin count and can award fixed values or jackpot prizes. The feature ends when no new symbols land or all positions are filled.
Coins Sniffer Hold & Win concentrates most payouts in its bonus rounds. Long dry spells are possible without feature activation, especially at higher stakes.
