HOW TO PLAY
How to play Straight Vault
Select a white cell and enter a digit with the on-screen pad or keys 1–6. Every uninterrupted horizontal or vertical white run must contain a gapless set of numbers in any order. Digits may appear only once in each row and column, including numbered black clues. Blank black cells block runs. Undo, restart, and check conflicts; solve a board to continue. Any rule-valid solution is accepted.
