Tsukuda's square

Quebra-cabeça simulador

On the left of each row is a plunger, which pushes that row one tile to the right. At the top is a large plunger which pushes the three rightmost columns down one tile. Press and hold the plungers with your fingers, once you release them they'll come back in to original position. You can press and hold up to five plungers at once, but please note if the top plunger is pushed in, the first row plunger can no longer move.

Please note: you must to PRESS and HOLD the plunger, NOT slide the plunger or press tiles.

This is simulator of original puzzle (invented by Toshihisa Suga, patented on 26 January 1983,), but it's unofficial version and neither the game or the developer is endorsed or related by inventors in any way.
