Orbium

Orbium is a one-touch marble puzzle by Björn Nilsson, originally released for iOS and now playable in any browser. You are a marble on an isometric tiled field. Tapping nudges you forward — and everything else on the board is a machine that reacts to you: rotators that swing you sideways, teleporters that jump you across the map, one-way lanes that only let you pass a certain direction, counters, clocks and stops.

It is written in plain JavaScript against an HTML5 canvas — no engine, no framework, no build step.

How to Play

1. Pick a level from the LEVELS menu (or press MENU).
2. Tap the marble to nudge it. Momentum carries it until something stops it.
3. Read the field: blue rotators turn you, teal rings teleport you, striped lanes are one-way.
4. Reach the exit dock on each level.
5. Press EDIT to build your own field from the same parts.

Controls

• Tap / click the marble — nudge it in the direction it is facing
• Arrow keys — nudge in a specific direction
• PREV / NEXT — step through the level set
• PLAY — start the current level
• MENU — back to the level list
• EDIT — level editor
• Touch controls appear automatically on touch devices

Tips

• Rotators move you regardless of your facing — plan the whole cell chain, not just the next tap.
• The clock mechanism advances on its own schedule, so some cells are only open for a beat. Waiting is often faster than tapping.
• Progress is stored per-level, so grinding one difficult level does not reset the others.

Save Data

Orbium stores your per-level progress in your browser's localStorage. Clearing site data will reset it.
