Editor review
Stack Frame is a deduction puzzle that respects the format. Sixty hand-built boards, a four-rule logic grid, and a hint system that gives you exactly one cell per board on demand. The constraint on hints is the right call. It keeps the boards honest and prevents the hint button from becoming a solver.
The board curve is the strongest part. Starters at 5x5, expert tier at 9x9, and the rule set scales rather than the board size doing the heavy lifting. By the time you reach the 8x8 tier the four-rule interaction matters more than the cell count.
I worked through about twenty boards across two evening sessions and a long Galway Galway bus commute. Each board takes three to seven minutes at the mid-tier. The save state preserves your in-progress marks per board, which matters for the longer boards.
Where I would push back is the visual layout on phones. The 9x9 boards crowd the screen and the cell-mark UI overlaps the rule list on smaller displays. A zoomable board would help. Four-and-a-half stars for a tightly-built deduction puzzle.
