Grid-logic deduction app for ages 9-14. How to Think teaches three deduction moves (one clue at a time; X for no and check for yes; one space left is the answer) with a coach-guided worked example. Puzzle Time holds six graded grid puzzles from 3x3 starters to two Detective-level 4x4 cases with linked grids, each with 4-6 clues, tap-to-cycle cells, a Check button that names one wrong cell without solving it, and sequenced hints that reveal one cell with its reasoning. True or Trick presents 8 valid-vs-invalid reasoning cards with plain-words explanations and a score summary.
