Ultimate TicTacToe Multiplayer vs PowerPlanner

You can play against the computer, a friend on the same device, or a real opponent. The goal is to make a row of three X's or O's before your opponent does. If you're looking for a new challenge, try the 5x5 or 7x7 versions, where the winning line must consist of 4 and 5 symbols respectively, instead of the usual 3.

Keep the lights on. PowerPlanner is a laid-back strategy builder where you grow a whole region's electricity network — one power plant, pylon and transformer at a time. Start with a single generator and a handful of homes. Wire them up across a blueprint-style map you can freely pan and zoom, then expand into factories, malls, data centers, hospitals and stadiums as demand — and your income — keeps climbing. BUILD A REAL GRID • Generators with character: diesel, solar (follows the day/night sun), wind (rides the changing weather), coal (and its CO₂ bill) and a full nuclear plant. • Connect everything with poles, transformers and batteries. Link range and transformer coverage actually matter — plan your layout. • Watch the power flow along your lines and keep every district supplied. RUN THE ECONOMY • A live commodity market for coal, oil, uranium, gas and propane with real-time price charts — buy low, sell high. • Dynamic building prices reward diversification over spamming one thing. • Manage fuel stocks, CO₂ costs and day/night demand swings. GO NUCLEAR • Cool reactors with water pumps and pipes, handle interim waste, and build shared waste repositories you can switch on and off. RESEARCH & UPGRADE • A 30+ node research tree: efficiency, income, grid range and building upgrades up to level 5. • Refineries turn crude oil into diesel, gas and propane to trade. PLAY YOUR WAY • Single-player, offline-friendly. No account required. • Cloud saves via Game Center keep your grid in sync across your devices. • Optimized for iPhone and iPad.
