Another variation on the tetris theme today – Blocksum, which is this clever, fun arcade puzzle game. Blocks with numbers in them rise slowly upwards. You can link blocks together to create sums – if enough blocks with equal sums are adjacent they’ll disappear and you’ll get points. It all seems simple enough till the pace increases and blocks with ever increasing initial sums start rising up. This is a great little diversion that takes a bit more skill than, say, solitaire. Windows only, free, for the downloading, and well worth a look.
