Elio Landa is rapidly becoming the name to look for if you like simple, elegant puzzle games, and Sum Points is all about subtraction-based math with a seriously swanky style. The goal is to get your target number to reduce all the way to zero by placing different coloured subtraction amounts on the grid around it. Blue sums impact everything in a diagonal line from their location, while red sums affect numbers horizontally and vertically from where you place them. It's important to note that sums will impact all numbers in a line, not just the first one their power encounters. You can see the sums you have available for each level at the bottom of the screen, and next to that is the undo button if you make any mistakes. Not that you would, you mathematical genius, you. Sum Point doesn't really offer a whole lot of variety to its gameplay, and focuses on making each level a neat little brain teaser, though it takes a while for it to have any sort of difficulty thanks to what might be a prolonged series of levels with training wheels on. With a soundtrack that makes it sound like you should be solving these while kicked back on a tropical island somewhere, Sum Points is a straightforward and casual experience for puzzle fans to relax with.
