Tangram Triangle Block Puzzle

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.
