Description

Each level names a target sum and gives you numbers on the board to reach it with. Dragging one number onto another combines them, and the level is cleared when what you are left with equals the target exactly — not close to it, exactly.


Some of those numbers are negative, and that changes the shape of the problem. In most number games the total only climbs, so going too far is fatal; here a minus is a way back down, and the route to the target can run above it before it settles.


That also means the order you combine in matters more than the arithmetic. The same set of numbers can reach the target or miss it entirely depending on which pair you merge first, and once two numbers are combined they are one number.


Fifty levels build from easy to genuinely awkward, and the early ones are gentle enough to work as a first introduction to negative numbers. There is no timer, so a level can be stared at for as long as it takes.
