Crucimates (La Vanguardia)
A crossword made of sums: place number tiles so every equation across and down works.
Every day: One cross-maths grid a day: place the number tiles so every interlocking sum across and down is correct. New puzzle: Once a day.

Crucimates is the daily maths puzzle on La Vanguardia's games page. The board is an 11 by 11 grid of interlocking equations, using addition and subtraction, laid out like a crossword. Some numbers are given; you place the remaining number tiles in the empty squares so every equation across and down comes out right, as fast as you can.
About Crucimates (La Vanguardia)
Crucimates, from cruci (crossword) and mates (maths), is a crossword where the words are sums. The board is 11 squares by 11. Running across and down are short equations such as a number, a plus sign, another number, an equals sign and a result. Where the equations cross, they share a square, so a number has to work in both directions at once. Blocked squares separate the equations, as black squares do in a crossword.
Some squares already hold numbers. The rest are empty, and you get a set of number tiles to fill them. The game's help text explains the goal: complete the board by placing the number tiles in the empty squares, solving the interlocking operations correctly and in the shortest time. Correct calculations turn green, and wrong ones turn red, so you see mistakes straight away.
On 3 October 2026 the grid used only addition and subtraction, with numbers from 1 to 18. The puzzle is timed, the game keeps your streaks, and it shows the average time and the share of players who solved the day's grid. Crucimates is one of the Quality Games puzzles on La Vanguardia's free games page, with a new board each day.
