You complete Doppelblock when the completed grid satisfies the two block latin sums 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.

Complete guide
Doppelblock uses the independently implemented Doppelblock two block latin sums rules profile v1 profile (R566). Doppelblock is a complete deterministic browser game whose distinct rules centre on Each row and column contains two blocks and every number once; outside clues sum numbers between the blocks. The independent runtime records this exact two block latin sums rules identity.
Doppelblock opens from a versioned seeded position built for Each row and column contains two blocks and every number once; outside clues sum numbers between the blocks. The independent runtime records this exact two block latin sums rules identity. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Doppelblock action is checked against the current board, available material, and this defining restriction: Each row and column contains two blocks and every number once; outside clues sum numbers between the blocks. Partial assignments remain legal only while at least one completion still satisfies those constraints. Invalid, stale, or post-terminal actions leave the position unchanged.
You complete Doppelblock when the completed grid satisfies the two block latin sums 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. Near the end of Doppelblock, recount the remaining obligations needed until the completed grid satisfies the two block latin sums 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.
A practical Doppelblock plan is to preserve several legal continuations around Each row and column contains two blocks and every number once; outside clues sum numbers between the blocks. The independent runtime records this exact two block latin sums rules identity. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Doppelblock error is to ignore the boundary rule that Each row and column contains two blocks and every number once; outside clues sum numbers between the blocks. 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.
Doppelblock has its own runtime and save identity because its rules require Each row and column contains two blocks and every number once; outside clues sum numbers between the blocks. The independent runtime records this exact two block latin sums rules identity.
Each row and column contains two blocks and every number once; outside clues sum numbers between the blocks. Partial assignments remain legal only while at least one completion still satisfies those constraints.
Doppelblock stores its game ID, rules version, and seeded deal identity. Those values recreate the same opening locally without promising that the position is forced or winnable.
