How to play
You complete Tren when the completed grid satisfies the sliding block mobility clues constraint set, every fixed clue, and the profile's whole-board completion test. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.
- Tren opens from a versioned seeded position built for Every numbered one-by-two or one-by-three block has the clued total mobility along its long axis. The independent runtime records this exact sliding block mobility clues rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Tren action is checked against the current board, available material, and this defining restriction: Every numbered one-by-two or one-by-three block has the clued total mobility along its long axis. Partial assignments remain legal only while at least one completion still satisfies those constraints. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Tren plan is to preserve several legal continuations around Every numbered one-by-two or one-by-three block has the clued total mobility along its long axis. The independent runtime records this exact sliding block mobility clues rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Tren error is to ignore the boundary rule that Every numbered one-by-two or one-by-three block has the clued total mobility along its long axis. Partial assignments remain legal only while at least one completion still satisfies those constraints. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Tren, recount the remaining obligations needed until the completed grid satisfies the sliding block mobility clues constraint set, every fixed clue, and the profile's whole-board completion test. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
