Robo-Link

About Robo-Link

Robo-Link is a wire puzzle on a small grid. A battery sits on one side and a robot on the other. Tap the tiles to turn them. Keep going until power flows all the way across and the robot lights up.

How to play

1. Find the battery and the robot on the board.
2. Tap a tile to turn it by a quarter turn.
3. Match the wire ends so each tile joins its neighbour.
4. Watch the powered tiles glow as the current spreads.
5. When the current reaches the robot, the level is solved.

What it practises

Each tile is a point and each wire is a link. Finding a route through them is a basic graph idea in computer science. The game has 10 levels. Grids go from 3 by 3 up to 5 by 5. Straight, corner, T and cross tiles all connect in different ways.
