Block Merge
Block Merge is a sliding crystal puzzle on a 5 by 5 board. Each swipe pushes every crystal as far as it can travel, grey stones stop them dead, and two matching crystals that meet fuse into the next kind. Every level has its own stone layout, one goal crystal and a fixed number of moves, so you plan around the stones instead of swiping at random.
How to play
- Swipe on the board, or use the arrow keys, to slide all crystals in one direction.
- Two crystals of the same kind that collide fuse into the next kind along the ladder at the top of the screen.
- Make the ringed goal crystal before the move counter reaches zero to clear the level.
- After each move a small crystal appears in a free cell, so the board slowly fills up.
- Stones never move. A stone in a row splits it into two separate lanes.
- You can undo a move twice per level. Fusing on several moves in a row builds a streak that multiplies your points.
Tips
Pick one corner and keep your largest crystal there, because a big crystal in the middle of the board blocks lanes. Before you swipe, check which lanes a stone cuts in two: a pair on either side of a stone can never meet along that line, so you have to route one of them around it first.
