The 7-Day Challenge

Day 5: Cyborg Cross 'N' Noughts

Tic-tac-toe, but every mark is dropped onto the board by the arm.

The challenge

Draw a tic-tac-toe grid on paper. On your turn, pick up a marker (a coin, a bottle cap, anything small) with the claw and drop it onto the square you want. Wherever it lands is your move.

Rules

  • Standard tic-tac-toe: three in a row wins.
  • If your marker lands on a square that is already taken, you lose your turn.
  • If it lands off the grid, you lose your turn.

Tip: the middle square is the easiest drop. The far corners are where games are lost.
