Arcade

11 games. Every one is free, needs no account, and keeps working with no connection once you have loaded it. Nothing is timed except the games that are about timing, and nothing is behind a wall.

• TETERI Block stacker · 1–2 players Pieces fall, rows burn, the stack climbs. Marathon runs, a CPU opponent at three difficulties, split-screen for two at one keyboard, and online duels over a five-character room code.
• BLOCKIE Grid puzzle · 1 player Drag pieces onto an eight-by-eight grid. Fill a row or a column and it clears. Nothing falls and nothing is timed — it ends when none of the three pieces in your tray will fit.
• SNAKE Arcade · 1 player Steer a growing line around a grid, eat what appears, and do not run into the wall or into yourself. Every bite makes it faster.
• MERGE Number puzzle · 1 player Swipe and the whole board slides. Tiles showing the same number fuse into their double. Reach 2048 before the board jams solid.
• BRICKS Arcade · 1 player A paddle, a ball, and a wall to take apart. Where the ball hits the paddle decides the angle it leaves at, so the paddle steers.
• MINES Logic puzzle · 1 player Open every square that is not a mine. Each number counts the mines touching it. The first tap is never a mine, so you always get a start.
• FLOOD Colour puzzle · 1 player The blob in the top-left corner takes whatever colour you pick, and swallows every matching cell it touches. Take the board before the moves run out.
• LIGHTS Logic puzzle · 1 player Press a cell and it flips, along with its four neighbours. Turn them all off. Every board is built from a solved one, so every board can be solved.
• PAIRS Memory game · 1 player Turn two cards. If they match they stay. The board grows with every level, and the turns you are given do not grow as fast.
• FOUR Board game · vs machine Drop discs down a seven-by-six grid and line four up before the machine does. It looks six moves ahead, so it will punish a lazy one.
• GLIDER One-button arcade · 1 player One button. Tap to rise, let go to fall, thread the gaps. They narrow the further you get, and nothing else about it is complicated.

They all work offline

Every game here is part of the same installable app. Add it to your home screen and it opens full screen with no browser chrome, and keeps working with no connection — the whole arcade is cached the first time you visit. See the TETERI guide for the rules and scoring of the main game, or the articles for the history and technique behind block puzzles generally.
