Totalock: Number Sum Puzzle
Logic puzzles with a twist
Totalock is a number logic puzzle. Every row and column shows a target: keep the digits that add up to it and erase the rest, and the line locks into place. Lock every row, column and cage to solve the board. It starts with small 4×4 grids and grows into color cages, times lines that multiply, product cages and 9×9 master boards. Every puzzle has exactly one solution you can reach with logic alone, and hints explain the next step instead of just giving it away. A new daily puzzle arrives every day, with a calendar, streaks and monthly trophies.

Totalock FAQ
How do you play Totalock?
Every row and column has a target. Use Lock to keep a number and Erase to remove it. When the kept numbers make the target, the line locks. Lock every row, column and cage to win.
Do I ever need to guess?
No. Every puzzle has exactly one solution, and you can always reach it with logic.
What are cages and times lines?
Color cages are groups of cells with their own target. On times lines and product cages the kept numbers multiply instead of add.
