Alien Pairs

The invasion has begun. A fleet of flying saucers is descending on your planet, and every saucer hides an alien. Your memory is the only weapon that can stop them.

Alien Memory Invaders is a memory matching game with a space-shooter twist. Tap two saucers to open them: if the same alien is inside both, your turret locks on and blasts them out of the sky. If they don't match, they close again and the whole fleet moves one row closer to the ground. Saucers that land open fire on your turret. Remember where every alien is hiding, clear every wave and keep your batteries charged.

★ HOW TO PLAY

• Tap a saucer to reveal the alien inside, then find its twin

• Every match fires the turret and recharges one of its batteries

• Every turn the fleet drops lower and new waves arrive

• Landed saucers shoot your turret, so destroy them first

★ 27 ADVENTURE LEVELS

Battle through levels that get tougher as you go. Earn up to three stars on each one and collect coins the first time you win.

★ MEET THE INVADERS

• Soot, Octo, Cyclops and Snail: the classic pairs

• Buzzer: miss it and it flies off to swap places with another saucer

• Grump: so tough that three must be open at once

• Robot: while it's on the field the fleet flips left to right, and in the final waves it can turn the whole fleet upside down

Every new alien appears on your radar screen before its first battle.

★ BOOSTERS

• Radar: reveals a matching set for a moment

• Freeze: stops the fleet for a turn

★ ENDLESS MODE
