Divide to conquer.

• A row of numbered tiles and a set of target sums.
• Tap between tiles to place dividers, splitting the row into segments.
• Each segment must sum to its matching target (left to right).
• One unique solution — no guessing.

Tap a gap to place or remove a divider. Targets turn green when their segment matches. Match all targets to win.

Start from the ends: the first target must be produced by a prefix of tiles, and the last by a suffix. Often only one split point works for the first or last segment — lock those and the middle falls.
