What's New in Hone Math
1.3.0
July 3, 2026
Construct gains an Advanced tier (Pro): exponents (^) and remainders (mod) join the tiles. Still always solvable, still quiet. NEW — Construct: we give you a target and a tray of number and operator tiles. Arrange them, left to right, to build the number. Every puzzle is solvable; the running total as you place each tile is the real training. Four tiers — the last two open with Pro. Your longest Construct streak joins the Records card. Quiet, like everything here.
