This game uses only virtual coins. No real money.
7x7 grid. A win is formed by 5 or more identical crystals touching horizontally or vertically (diagonals do not count). Tiers: 5 / 6-7 / 8-9 / 10-14 / 15-19 / 20-24 / 25+.
Winning crystals disappear, gems above slide down, and new ones fall into empty spaces. Cascades continue as long as new clusters form. All wins per spin add together.
The Rainbow Prism substitutes for any crystal. Each prism starts at x1 multiplier. After each cascade where the prism was in a cluster, its multiplier increases by +1. Multiple prism multipliers multiply together. After each cascade series, every prism takes one random step.
3 or more prisms on screen after a spin triggers 6 free spins. During free spins, prisms are sticky: they stay on the grid with their multipliers and wander each spin.
The game uses only virtual coins with no real value. Balance can be restored on the game screen.
