About the game
Each stage is a square grid, a bit like a small board of letters and dashes. Some cells already hold a magnet, shown in grey as "N", a few dashes and an "S", and some are blocked by "#". Your job is to cover every remaining empty cell with more magnets. A magnet is a straight bar of at least three cells with its north pole (N) at one end and its south pole (S) at the other.
The one rule is that a north pole may not sit next to another north pole, and a south pole may not sit next to another south pole, in any of the four directions. That sounds easy until the grid fills up and the last few gaps only fit in one way. You place a magnet by dragging from where the N should go to where the S should go, and a tap on one of your magnets takes it back off the grid. A timer runs from the first stage to the tenth, and the grid gets a little bigger as you go.
Magnet Blocks is one of the one-button mini-games that Kenta Cho, who works as ABA Games, makes with his crisp-game-lib library. There are no image or sound files: the graphics are drawn by the code, and the sound effects and music are generated while you play.
Playing it here
Click Play, then click or tap inside the game to start. The clock at the top left runs through all ten stages, and the counter at the bottom left shows which stage you are on. Nothing is installed or sent anywhere. The best score at the top right is only remembered while the page stays open.
Controls
| Input | Action |
|---|---|
| Drag (mouse or touch) | place a magnet from its N end to its S end |
| Tap one of your magnets | take it off the grid |
A few things worth knowing
Start from the tightest corner. A cell with only one free neighbour can only be the end of a bar.
Mind the red X. While you drag, an X means the spot is not allowed: wrong direction, too short, or a like pole next to it.
Do not be afraid to undo. A tap on a placed magnet removes it, so try a layout and take it back if the rest does not fit.
