Afterbot
One command behind, together
Free · Designed for iPad. Not verified for macOS.
Red follows your command. Blue follows the last one. Can you bring them home together?
One robot follows your command. The other follows your previous one.
Guide two little robots to their matching charging pads. Red 1 moves in the direction you press now. Blue 2 moves in the direction you pressed one turn ago. They receive the same instructions, yet they drift apart. Turning that drift to your advantage is the whole game.
WALLS ARE NOT OBSTACLES
A robot that hits a wall or the edge of the board stays where it is - but the command is still remembered, so its partner will take that direction on the next turn. Deliberately stalling one robot to bank a step of delay is the core technique.
CHAPTER 1 - LEARNING TO LAG (48 experiments)
The first stage takes two presses. The second teaches you stalling. From there the routes grow gradually longer.
CHAPTER 2 - PICKING UP PARTS (24 experiments)
Parts are scattered across the board, and you must collect every one before docking. Either robot can pick them up, so the puzzle becomes about routing your one-turn-late partner over them along the way. Reaching the pads with parts still on the board is not a clear.
TOOLS FOR THINKING
A glowing frame shows where Blue will move next. The shortest known solution is displayed, and clearing it without hints earns a star. Undo any number of moves. Progress saves as you go. Play with the arrow buttons or by swiping the board.
A new daily experiment with two parts is generated every day.
