How Upgrade Mechanics Work

The core feature revolves around symbol transformation during gameplay. When special icons land on the reels they can upgrade adjacent elements to higher-paying characters. This process happens automatically without player input. Multiple upgrades can occur in a single spin. The title uses a cascade system where winning combinations disappear. New symbols drop down to fill empty spaces. Additional wins can form after cascades complete. The upgrade feature remains active throughout all cascade sequences. Players experience continuous action until no new matches appear. Wild icons substitute for all regular characters except bonus elements. These wilds also participate in the upgrade mechanism. When a wild gets upgraded it applies multipliers to any wins it helps create. Multipliers range from 2x to 10x depending on upgrade level.

Bonus Features and Purchase Options

The activity at Casushi includes three distinct bonus elements that enhance gameplay:

1. Free Spins Mode — Land three or more scatter icons to trigger this round with 10 initial spins
2. HyperBonus Buy — Purchase direct access to bonus rounds at varying cost levels
3. K-Boost Technology — Increase bet size by 50% to double scatter appearance rates

Free spins carry enhanced upgrade potential compared to base game action. During this mode every winning cascade increases a multiplier that applies to all subsequent wins. The multiplier starts at 1x and increases by 1 after each cascade. No maximum limit exists on multiplier growth during free spins. Users can retrigger additional spins by landing more scatters during the bonus round. Each retrigger adds 5 extra spins to the current total. The multiplier value persists through retriggers and does not reset.

Betting Range and Technical Details

Minimum stake starts at £0.40 per spin for UK players. Maximum bet reaches £20.00 per spin for higher rollers. The title supports both desktop and mobile devices through HTML5 technology. Loading times remain quick across all platforms. Hit frequency sits at approximately 28% meaning roughly one in four spins produces a winning combination. Bonus rounds trigger on average every 180 spins during regular play. The K-Boost feature reduces this frequency to roughly every 90 spins. Maximum exposure per spin equals 5,000 times the stake amount which translates to £100,000 at max bet level.
