Robot-arm puzzle

GRIFF

“Program the arms. Press start. Watch them work.”

Stores hand out coloured tiles, outputs want particular stacks. You set up robot arms and give each one a short program of command keys. Then you press start: all arms work at once, tick by tick, repeating their programs over and over.

How it works

Set up, program, start

  1. Set up the arms

    Stores hand out coloured tiles, outputs want particular stacks. In between you set up robot arms.

  2. Program them

    Give each arm a short program of command keys: turn, grab, drop, extend, wait.

  3. Press start

    All arms work at once, tick by tick, repeating their programs. Few commands and few ticks earn stars.
