Turn up the heat.
A Japanese hot spring where a capybara takes the long bath. Every winning square heats up and doubles its multiplier, squares at ×8 boil over and clear their neighbours, and in the hidden spring the heat never leaves the board.
Heat builds where the wins land — and in the hidden spring, it stays.
Five or more matching symbols touching horizontally or vertically pay as one cluster on a 7 × 7 board. Winning symbols clear and the board tumbles until nothing connects.
Every square that hosts a win heats up. Hit it again and its multiplier doubles — ×2, ×4, ×8 and on up to ×1,024 — under any cluster that pays across it.
Squares that reach ×8 boil over: the steam clears the neighbouring symbols, opening the board for the next tumble to land on hot ground.
Three, four or five torii gates open 10, 12 or 15 free spins in the hidden spring, where heat stays on the board for the whole feature. Five buy tiers go up to The Boiling Spring.
