Panes

Classic 75-ball bingo, you against Claude. Numbers are called, you mark your card and shout Bingo first; Claude plays a card of its own and claims one call late, so you get a fair window. Zero tokens.

Connect Four against Claude, in a pane. Press a column's digit to drop a disc; Claude answers in half a second at three levels, from beatable to a seven-move lookahead. Zero tokens.

The Chrome dinosaur runner in a pane. Press w to jump the cacti; the ground speeds up as you go, and your best distance is kept. Zero tokens.

2048 in a pane. Slide tiles with w, a, s and d, merge equal numbers, reach 2048. One undo, a best score that survives restarts, and a board that replays from its seed. Zero tokens.

Choose which MCP tools and subagent types Claude sees, per project. A pane lists every server and tool with the size of its description; defer or hide the ones this repo never needs and stop paying for them on every request.

Memory pairs in a pane. Sixteen face-down cards, eight matching pairs; press a card's letter to turn it, find its twin, finish in as few turns and as little time as you can. Best of each kept. Zero tokens.

Snake in a pane. Steer with w, a, s and d, eat the food, don't hit the walls or yourself. Pause with p, pick the speed, high score kept. Zero tokens.

Sudoku in a pane. Three levels with one solution each, move with w a s d, type a digit, undo, a hint when stuck, and a clock that pauses when the pane closes. Best time per level kept. Zero tokens.

Typing race in a pane. A line of code appears, you type it; every character colors right or wrong as you go, and Enter scores words per minute and accuracy. Last ten runs and your best kept. Zero tokens.

Tic-tac-toe against Claude, in a pane. Press a digit to play a square; Claude answers in half a second at three levels, from beatable to perfect. Zero tokens.
