About Merge Blocks

You drag numbered blocks from a supply tray onto a five-by-five grid, placing them wherever you like. Match three or more identical blocks that touch—horizontally, vertically or in clusters—and they merge into a single block of the next tier. Each merge clears space and lets you drop more pieces, so planning your layout matters: a smart cascade can clear half the board in one move. The goal is to build the highest-value blocks you can before the grid fills and no legal moves remain.

Poki Games hosts this puzzle that blends spatial Tetris-style placement with 2048's exponential scoring. Three power-ups let you undo a bad drop, detonate unwanted blocks or double your points for a turn. Watching chain reactions ripple across the board—where one merge triggers another, then another—is the reward for thinking two or three moves ahead.
