Sudoku, with magical shapes
Shapedoku is a puzzle game built on a simple idea: keep everything that makes Sudoku great, and swap the numbers 1 to 9 for nine glowing shapes. The rules never change. Every row, column and 3 by 3 box still needs each symbol exactly once. Only the look changes, and that small change makes the board friendlier to read and a little more magical to play.
Why shapes
Numbers all share the same footprint, so a busy grid takes real effort to scan. Shapes differ by their whole outline, which the eye recognizes almost instantly. They are also kinder to colorblind players, because every token is distinct by form as well as color. The result is a calmer, more welcoming puzzle that still delivers the exact same logic.
