Glide Bots
A sliding-robot puzzle. Robots never stop halfway — they glide until something blocks them. Use walls and the other robots as stoppers to land the named robot exactly on its ring.
Slide robots that only stop at walls or each other, until the right robot comes to rest on its target.

On the board: 1–3 choose a robot; W A S D slide it (the arrow keys move the focus). Dots preview where it would stop.
Par is the proven shortest number of moves, found by searching every reachable position.
Controls
- Choose a robot with its button, by tapping it, or by pressing 1, 2 or 3 on the board.
- Slide it with the on-screen arrows or W, A, S, D on the board. Dots show where it would stop; tapping a dot slides it there.
- Undo takes back a move, Reset starts the board again, Hint suggests the next move of a shortest solution from where you are.
The rules
- A robot slides in a straight line until its next step would hit a wall, the edge or another robot.
- A slide that wouldn't move the robot at all doesn't count as a move.
- Only the named robot can win, and only by stopping on the ring — gliding over it does nothing.
Scoring, saving and limits
Fewer moves is better. Par is the proven shortest solution, found by checking every reachable position. Using a hint marks the run as assisted.
Your moves on the current board and your best result per board are kept on this device only. Download a backup to move them.
Twelve generated 8 × 8 boards; each par comes from a search that finished. Hints search from your current position and may say the search ran out of budget.
Questions
- Why didn't my robot stop on the target?
- Robots only stop when blocked. Put a wall or another robot just past the target first.
- Is par really the minimum?
- Yes — the generator searched every position reachable from the start until it found the goal, so nothing shorter exists.
- What do the dots mean?
- They mark where the selected robot would come to rest for each direction it can move.
