This one swaps the usual race against gravity for something calmer. Pixel Tetrix Trails gives you a set of glossy Tetris-style pieces and an empty outline, and you have to rebuild a pixel-art picture out of them before the timer ends. When the last piece clicks in, the image is revealed.
There are 90 handcrafted levels, set in a cozy artist-studio look, and each of them has a clock running. It is a pleasant mix of a jigsaw and a block puzzle. Tetris-style pieces in their traditional job can be found in Tetris 1989.
