PixPlus

In PixPlus, based on the logic game Kakurasu, you're given a total of 16 puzzles to solve in a random order. Each puzzle has a time limit, which gets tighter as the stages progress. 8x8 PixPlus boards are divided into smaller 4x4 boards, and you have to solve them all to beat a stage. At the end of each puzzle, these smaller boards get combined to reveal a small drawing.

The main mechanic of PixPlus is addition. The larger numbers on the edges of the boards show the expected result of the sum on that row or column, and the smaller numbers show the value of each position. To form 8, for example, you should fill squares on the positions 1,3 and 4, since 1+3+4=8.
