Ternary Reach
Borrow a higher number’s reach, fuse exact triples, and deliver all27 mass to the altar.
How to play
Tap a number, then a highlighted destination. A swap must create a straight triple and may borrow the larger reach of EITHER swapped number:1 reaches one Manhattan step,3 reaches two,9 reaches three,27 reaches four. Equal-number swaps do nothing and are not offered. Every exact triple becomes one triple-valued number at the destination if it belongs to that line, otherwise at the first cell of that line; newly formed triples cascade. Total mass stays27 and the board never refills. Once27 exists, move it through empty cells within reach to the TOP-LEFT ALTAR. Finish within nine committed swaps; source selection and Cancel are free. Undo restores a prior swap before terminal outcomes; restart after failure.
