Equaboard: Math Crossword

Educate Labs

About this game

Equaboard is a calm math crossword puzzle game. Fill the board with number tiles so every crossing equation is correct, across and down. Every board has exactly one answer, and you can always reach it by pure logic. No guessing needed.

HOW TO PLAY
It works like a classic crossword, but with numbers: a true math crossword. Each board is a grid of crossing equations with empty slots. Drag a number tile from the tray into a slot, or tap a slot and then a tile. When an equation is right, it glows with a check mark. When it is wrong, it gives a gentle shake. Move, swap or return any tile at any time, and undo every step.

A MATH PUZZLE THAT GROWS WITH YOU
Start with simple addition and subtraction. New ideas arrive one at a time: crossing equations, decoy tiles that do not belong, multiplication, bigger boards, division, hidden signs, locked slots and shaped boards. Every 10th level is a boss board. There are more than 1,000 levels, and new boards keep coming after that.

SPOT THE DECOYS
Not every tile in the tray belongs on the board. Work out which numbers fit and which are decoys. It turns a simple number puzzle into a real logic puzzle.

A NEW DAILY PUZZLE
A fresh daily math puzzle every day: gentle on Monday, toughest on Sunday. Keep your streak going, and do not worry about one missed day: a rest day keeps your streak safe. Past daily puzzles stay playable.

HINTS THAT TEACH
Stuck? A hint explains the next logical step instead of just giving you the answer. Notes mode lets you pencil in candidate numbers, just like in Sudoku.

15 BEAUTIFUL BOARDS
Choose your board: Honey Oak, Marble, Crystal, Lagoon, Jade, Coral and more. The whole game takes on the colours of the board you pick.
