KEEPERS! Both this and it's larger version are main stays on all my tec. .I play this smaller game almost every time l open my phone . There is more skill than is first apparent and Although the colours vary in both games l would like to see the coloured squares darker, I do find myself confusing the red and the orange at night . Apart from this the game is very good and I recommend it!
Fun game. Bug free. No creepy unnecessary permissions. No ads. What more can you ask for in an app?
Changed game-rule: the penalty applies to the first and later mistakes.
