Eighty-Eight is an incredibly simple yet incredibly addictive puzzle title that's inspired by classic number logic games like the ever-difficult Minesweeper.

Your aim, then, is to strategically drop numbered tiles onto the on-screen game board in order to set off bombs and create chain reactions that will - hopefully - nab you a high score.

There are two different game modes to master in Eighty-Eight: Normal, which is fairly relaxed; and Speed, which - as it name suggests - is pretty fast paced.

Your aim in Stupid Zombies 2 - as it is in pretty much every zombie-filled game - is to wipe out waves of geeks, walkers, biters, and flesh-eating corpses.

You do this across 500 action-packed levels with some good old-fashioned bullets and a bunch of environmental hazards, such as explosive red barrels.
