The Rainbow Blast is the only chargeable power-up in the game. Charge it by exploding power-ups - it appears once it's fully charged! 🌈

Swap it with another piece to clear every piece of that type. Even better, match two Rainbow Blasts together to clear one entire layer from the field 🔥

IMPORTANT NOTE:
Charging speeds can vary between levels - charge it faster by exploding several power-ups at once 💪
