Math Crossword Puzzle Genius Edition and the missing-number equation grid
In Math Crossword Puzzle Genius Edition, you fill one missing number in each equation by choosing the right tile from a side panel, then placing it into a crossword-style grid. Addition, subtraction, multiplication, and division all appear in the same board, so every move depends on reading the row, checking the column, and spotting the value that makes the math work. It runs free online in your browser, with no download and no signup.
This fits neatly inside logic games because the answer is never random: the grid itself tells you where each number belongs. If you like math games, the appeal is the constant switch between arithmetic and deduction, especially when a short equation forces you to test several possibilities before you commit.
Correct picks add points, and the game also lists Daily Tasks, Boosters, a Season pass, hundreds of levels, and many languages, so there is plenty to work through after the first few boards. For another equation-first challenge, Math Master is similar because it also asks you to solve number problems by reading the board carefully. Sum Master is a close match too, since its arithmetic targets reward the same kind of placement logic. Number Match shares the same number focus, but it leans more on quick pairing and pattern spotting than on building complete equations. Click a number, then click the matching grid spot, and you can keep the pace steady on desktop or mobile-friendly play.
