Achromatic! vs Japsum

Achromatic is a minimalist puzzle game about connecting dots in order to transform them all to one cohesive color. Draw a straight line between two dots of the same color to paint the dots between them. However, you can only change dots of one color at a time. You'll quickly encounter unique dots with exciting properties. For example the square dot lets you change the direction of your line, or the triangle dots are synchronized such that changing one of them changes all of them. Achromatic features an original and relaxing sound track to accompany its polished minimalist aesthetic. Its smooth difficulty curve will teach you the mechanics and gently ease you into more difficult levels. All levels were carefully designed by hand to ensure the best puzzling experience possible. For those craving a challenge, bonus levels are available after beating the game to really test your logic skills. Features: • 60 handcrafted level plus 10 challenging bonus levels • Unique dots with special properties • Supports both vertical and horizontal orientation • Color blind mode

Japsum (short for "Japanese Sum") is a free, logic-based, combinatorial number-placement puzzle game. It’s similar to Kakuro or Sudoku puzzles, but with its own unique twist. Starting with an empty grid, you’ll use hints provided on the sides and top to place numbers or black boxes in the grid. The hints indicate the sums of consecutive numbers, with no black boxes in between. Multiple hints mean that sequences of numbers are divided by one or more black boxes. By using logical reasoning and interpreting these hints, you’ll make steady progress in filling in the grid with numbers and black boxes. Be prepared—especially with the larger grids, these puzzles can get very challenging! The app offers grid sizes ranging from 3x3 to 22x22—the largest puzzles of this kind, as far as I know. Every puzzle has exactly one unique solution, ensuring a fair and rewarding challenge. As you solve puzzles, your level increases, unlocking larger grids and fun bear avatars that you can choose to represent your progress. Best of all, Japsum is completely free—so you can dive into the world of Japanese Sum puzzles at no cost. Are you ready to test your logic and take on the ultimate puzzle challenge?
