You bring down blocks from the top of the screen. You can move the blocks around, either left to right and you can rotate and mirror them. You have to build the box to fill the rows to remove the completed line. You can make them fall faster if you’re sure of your positioning. And collect the score.
A typical puzzle session starts slow. You look at the board, work out what the rules actually are, and make a tentative first move. Then the pattern clicks and the next few stages go quickly, until one stops you cold. That rhythm, easy then stuck then easy again, is the whole appeal. Most sessions last ten to twenty minutes before you reach a natural stopping point.
Tetris 3D rewards patience more than reflexes. Nothing punishes you for taking a minute to think, and the moment a hard stage finally gives way is worth the wait. It runs free in your browser with no download, so it is easy to pick up for a short break and leave again.
People who like to think rather than react, anyone killing time on a commute, and players who want something quiet to do with one hand on a phone. Younger children may need help with the trickier stages.
