How to play

Mark the numbers to add up with a star and cross out the ones to eliminate.
The target sums of each row and column are shown on the edges of the grid.
Each coloured region also has its own sum, shown in the top-left corner of its first cell.
Every generated grid has a unique solution, found by deduction.
