How to Play Tandem

Tandem is a grid-based puzzle game where you control two holographic avatars at once. Every arrow key (or swipe on mobile) moves both the Cyan twin and the Magenta twin in the same direction simultaneously. If one twin is blocked by a wall, only the other moves — this wall-pinning mechanic is the core of every puzzle solution.

Each twin has color-matched goal pads on the grid. Solve a level by getting both twins onto their own color pads at the same time. Along the way, push prism crates onto the pads to create bridges and block your partner's path. Anchor crates (gold) lock permanently once placed on a gold target — plan ahead.

Tips and Strategy

• Pin one twin to separate the pair. Walking a twin into a wall makes the next input move only the other twin. Use wall-pinning intentionally to split the pair, then reroute one twin to its pad without dragging the other.
• Solve the harder twin first. If only one twin has a tight path full of crates, route it onto its pad before the easier twin moves into a blocked corner. The pad does not need both twins simultaneously until the very last input.
• Place anchor crates only when certain. Gold anchor crates lock permanently on gold targets, and freeing them costs an extra move plus breaks the lock bonus. Test the route with undo before committing the anchor.
• Chase par for the +50 bonus. Par is shown at the top during play. Hitting par awards +50 points; staying within par × 1.5 still earns +25. Undos forfeit the +30 frugality bonus and restarts forfeit the +20 first-try bonus, so plan moves before pressing.
• Undo, never restart. Undo (U or Z) is unlimited and preserves the first-try bonus path; restart wipes both. When a crate jams into a corner, rewind one step at a time rather than resetting the level.

Controls

• Arrow keys / WASD — move both avatars
