Arcade

Every game here is free, needs no account, and keeps working with no connection once you have loaded it. Nothing is timed 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.

Which one should I play?

TETERI is the one with pressure. Gravity sets the pace, it speeds up as you clear, and versus modes let you send garbage rows at somebody else. It rewards fast hands and pattern recognition.

BLOCKIE is the one you can put down. There is no clock and no falling, so a turn takes as long as you want it to. The whole game is deciding where three awkward shapes go without painting yourself into a corner. It rewards looking two moves ahead.

They both work offline

Both games are installable. Add either to your home screen and it opens full screen with no browser chrome, and keeps working with no connection — the whole thing is cached the first time you visit. See the TETERI guide for the rules and scoring, or the articles for the history and technique behind them.
