Red Stone is one of the best square-shuffling games on Android and one of the hardest. You start off with a big fat 'King' square that's four times of the normal 'pawn' squares, then set about shuffling things so the fat King can get through to an exit at the top of the screen.
It's hard to accurately describe a puzzle game in the written word, but seriously, it's a good game.
Newton is a maths/physics challenge that has you lining up shots at a target - but having to contend with the laws of nature, in the form of pushers, pullers, benders (no laughing), mirrors and traps, all deflecting your shot from its target.The developer is still adding levels to it at the moment, so one day Newton might be finished and might cost money. But for now it's free and a great indie creation.
Sketch Online is a sociable guessing game where users do little drawings then battle to correctly guess what's being drawn first. It's like Mavis Beacon for the Bebo generation. The version labelled "Beta" is free, and if you like it there's the option to pay for an ad-free copy. But Google can't make you. Yet.
Drop a game, others might classify it as a tech demo that illustrates the accuracy of the Android platform's accelerometer, thanks to how playing it simply involves tilting your phone while making a little bouncy ball falls between gaps in the platforms. Either way it'll amuse you for a while and inform you of the accuracy of your accelerometer - a win-win situation.
Frozen Bubble, is based around the ancient and many-times-copied concept of firing gems up a screen to make little groups of similarly coloured clusters.
Abduction is a sweet little platform jumping game, presented in a similarly quirky and hand-drawn style as the super-fashionable Doodle Jump. You can't argue with cute cows and penguins with parachutes, or a game that's easy to play with one hand thanks to its super accessible accelerometer controls.
Cestos is sort of a futuristic recreation of curling, where players chuck marbles at each other to try and smash everyone else's balls/gems down the drain and out of the zone. The best part is this all happens online against real humans.
Air Control
Air Control is one of the other common themes on the Android gaming scene is clones of games based around pretending to be an air traffic controller, where you guide planes to landing strips with a swish of your finger.
