Core Blocks
A block puzzle you already know how to play — and a merge game hiding underneath it.
Fit the pieces onto the grid. Fill a row or column and it clears. But every line you clear also forges a gold core, and matching cores fuse: 2 into 4, 4 into 8, up to 64. Spend a 32 to reroll your pieces. Spend a 64 to blast a hole through the board.
