Reel strips
Base symbols are generated from explicit 40-stop reel strips: one random stop is selected on each reel and three consecutive symbols are displayed.
Whack & Win bonus
A coin on reel 3 together with a Hammer on reel 2 triggers the feature. Mini reels above the columns assign 1–3 hammer strikes. A struck coin is collected and leaves a multiplier marker in that cell. New coins landing on marked cells are multiplied. Every successful collection resets the 3-spin counter; an empty round reduces it by one.
This portfolio/demo build recreates the public-facing mechanic and visual direction with original code and CSS artwork. MULTISPIN runs large mathematical simulations (for example 1E6 spins) with no reel or bonus rendering. It does not copy proprietary game assets or certified production mathematics.
