I have developed a game, "Poke the Circles". The game is very simple yet challenging!
In this game, you poke the circles in the order they appear, and in any level N you can poke a circle only if there are more than N circles on the screen at that time!
The game is quite fun and addictive, and also exercises your memory, concentration and reflex.
