Play Deblock (Japan) Online
Dropping blocks from any side of the screen turns Tetris logic upside down—you’ll catch yourself tilting the controller trying to find the right angle before the stack collapses. That NES soundtrack burrows into your skull while you overthink every chaotic placement.
Deblock is a Japan only puzzle game for the Nintendo Entertainment System, released in 1990 by publisher Irem. It arrived late in the NES lifecycle, a time when developers were still finding new ways to challenge players within the system's familiar constraints.
You control a cursor that picks up and drops colored blocks from any of the four sides of the screen. The main objective is to clear the playfield by matching four or more blocks of the same color, but the twist is that you can only drop a block from the side you picked it up from. This forces you to constantly rotate your perspective and plan several moves ahead as the stack grows more precarious. The pacing is methodical at first but quickly becomes frantic as the blocks pile up. It feels like a constant, satisfying battle against your own spatial reasoning.
