Planets on cards, hidden face down, and a clock that keeps ticking. Here you reveal two cards at a time and try to remember where each world is hiding, which makes it a neat little workout for your short-term memory.
Each round has three phases that grow in size, starting with three pairs, then six, then nine. Positions are shuffled every time, so you cannot rely on old memories, and the timer rewards a faster finish. It is free in the browser, with a mouse or touch to flip cards, and no download is needed.
