How to play
Complete Arrow Flow when every editable decision satisfies the numbered arrow successor route constraints together. The runtime checks the entire position rather than a visual approximation or an unsupported solvability claim.
- Arrow Flow reconstructs its published opening from the route ID, rules version and local seed. Fixed clues, hidden cards and editable decisions remain separate, and restart reproduces the same position without a network request.
- The bounded checker rejects a finished grid unless follow each numbered arrow to the next number and use every route position exactly once. Invalid, stale, non-finite and post-terminal actions leave the state and undo history unchanged.

Strategy tips
- Start Arrow Flow with the most constrained exposed obligation, then preserve a second legal route before committing the first. Follow each numbered arrow to the next number and use every route position exactly once.
- Do not treat a locally tidy move as proof of progress in Arrow Flow; it can consume the only route that still satisfies the full boundary rule.
- Near the end of Arrow Flow, count every unresolved destination or constraint before committing a narrow move. Use undo to compare legal branches, then recheck that every editable decision satisfies the numbered arrow successor route constraints together.
