Six small, classic games you can play directly in this tab: Tic Tac Toe against a local computer opponent, Retro Snake, Memory Match, the Color Match Stroop reaction game, 2048, and Minesweeper. Every game runs entirely in your browser, so a round starts the moment you open it.
Only 2048 does, storing your best score in the browser so it persists across visits on that device. The other five games track your current run only and reset on reload.
No. Every game accepts touch input as an alternative to a mouse and keyboard, so they are all playable on a phone or tablet.
Tic Tac Toe supports a local two-player mode where you share one device and take turns. The other five games are single-player.
No. They run as part of this web page with no separate download, install step, or app store listing required.
