QMentat helps you practice mental arithmetic. It uses arbitrary-length fixed point arithmetic, and can handle any size numbers, only limited by the size of your screen (and in the case of division with an integer result, the speed at which the number can be factored). It is also quite configurable, allowing you to tailor the questions to your needs.
Pocket Bandit is a slot machine game for Android. It features a retro style with three reels and ten stops, and is modelled after the classic, mechanical fruit machines of the early 20th century and emulates devices such as the Mills Novelty QT Chevron, Mills Novelty Vestpocket, Groetchen IMP trade simulator, Pace Comet, and Liberty Bell. Unlike the original machines, it also includes elements of skilled and strategic play. You can spin the reels at different speeds by pulling the knob at different speeds, stop a reel at will by yanking the knob up, wager zero to three coins per round, and use no-wager rounds to skip over bad luck streaks.
Erebus is a 2D real-time role-playing game. Though in its early stages, it is already playable with three quests.

EPIC is a multiplayer strategy roleplaying game in which you are pitted against or work with real people in various fantasy settings called modules. It starts with Conan and Malazan modules. Third parties can create new modules. The system supports adventures, armies, characters, assassins, guilds/buildings, very rich magic (over 400 spells) and over 2,000 items, in a realistic fantasy world . The game focuses on minimum game time but the maximum amount of time thinking about the game and your cunning plans with your allies. There's no farming or repetition. The game format encourages the creation of epic fantasy tales. Part of a player's turn is in real time, but movement and military orders are done as submitted orders which are processed as your turn.
