How to Play
Getting Started

The Torus Games are easy to use and largely self-explanatory. Just pick a game and start playing! If you don’t yet know what a torus is, start with the Pool game to see the wraparound effect immediately. The wraparound effect works the same way in all the other games as well.

Mouse cursor

Click on the board to get a hand cursor. The hand cursor lives on the torus and wraps around automatically. Double-click to restore the usual arrow cursor.

Scrolling

Grab the background in any game and drag it with the hand cursor. The whole board will scroll. Drag with two fingers to scroll the board.

Crossword: How to Play in Klein Bottle

Klein bottle crossword puzzles have no consistent sense of left or right. As you scroll the board, a single word may read left-to-right at some times and right-to-left at other times. An arrow shows you which direction the word should go.

Words in a torus always read left-to-right.

Word Search: How to Mark Words

As you find each hidden word in the Word Search puzzle, drag the mouse to select it. drag your finger along the word to select it. If you need to adjust the word's endpoint, move the blue dot. Then tap the blue dot to finalize your selection. Words may go up, down, left, right, or diagonally.

Chess: How Pieces Move

Pieces move exactly as in regular chess, except that pawns may move one space up, down, left or right when not capturing, or one space along any diagonal when capturing.

Apples: How to Play

Eat all the good apples, but avoid the wormy ones. Each time you eat a good apple, you’ll see how many of its eight neighbors are wormy. Left-click on an apple to eat it or right-click to mark it as wormy (on Macs, right-click = ctrl-click = 2‑finger click on trackpad). Tap to eat an apple, or long-press to mark it as wormy.
