Strap on your comfiest thinking cap, youâ€™re going to be wearing it a while! The iball3 is a handheld puzzle game thatâ€™s so simple, but so infuriatingly tricky, that itâ€™s impossible to put down.
The little blue ball has six light-up buttons â€“ each of which could be red, blue or green. Pressing them changes their colour, but not in a predictable cycle. No, the aim of this game is to work out which ones to press in sequence to turn them all the same colour.
