How to play
Finish Rectslider when every cell, edge, region, and fixed clue satisfies the clue distance rectangle movement completion test. Completion is checked from the entire position, not from a displayed answer or a visual approximation.
- Read the opening of Rectslider by locating every lane, clue, reserve, room, or fixed element named in its rule. Slide each clue along a straight route by its stated distance, without route overlap, so all destination cells together fill one rectangle. The seeded deal and rules version reproduce that public starting information without exposing a hidden completion.
- Check each proposed action against the current position and this boundary: Slide each clue along a straight route by its stated distance, without route overlap, so all destination cells together fill one rectangle. Illegal, stale, and post-finish actions are rejected without changing the board.

Strategy tips
- List the straight destinations at each clue distance, then choose a compatible set whose endpoints can form one rectangle without route overlap.
- Selecting endpoints that outline a rectangle but leave a hole or crossed slide path satisfies the silhouette while violating destination coverage.
- During the final few decisions, compare every unresolved obligation with the target: every cell, edge, region, and fixed clue satisfies the clue distance rectangle movement completion test. Keep the option described in the strategy note available until the last forced dependency is settled.
