There are not many games on the iPad that lets you play multiplayer games on the same iPad simultaneously. But Pickadot is one of those games. It’s a fast paced multiplayer action that lets up to 4 players play on the same iPad.
Every player is assigned a dot with a color. Then there will be dots spawned on the screen and every player is to take the dots with the same color as their own dot. There are bonus objects in the game as well that will give boost to you as you drag them to your own dot or punish your rivals when you drag them to their dot.
