Angry Birds, Flappy Bird and Plants Vs Zombies are among the most addictive mobile games in history, but one simple game is set to join that list.
A free app, available on both Android and iOS.
The maths based game presents the player with a screen full of times and the objective is to swipe the tiles to add numbers until the user reaches tile 2048, but before the board gets full.
As with Flappy Bird et al, it's the perceived simplicity of the game that gets users hooked. It's a great time killer on the daily commute, but still requires brain power.
