Kakuro Logic Puzzles, developed by Topleftsoft LLC, is a free puzzle game available on Android. Kakuro, also known as Cross Sums, is a popular logic-oriented numeric puzzle game that is as addictive as Sudoku. The objective of the game is to insert a digit from 1 to 9 in an empty cell so that the sum of the numbers in each entry matches the clue in the small triangle above or to the left. Each digit can only be used once in an entry, and every puzzle can be solved with pure logic, having only one correct answer.

This app has a simple and intuitive user interface with brainteasers ranging from easy to hard, featuring 5x5, 7x7, 9x9, 10x10, and 13x13 grids. Topleftsoft LLC adds new Kakuro puzzles regularly, making this app a great way to train your brain and sharpen your logical thinking and solving skills. The puzzles are handmade, and the game supports zooming and saving functions, as well as manual note-taking. The app also features a hint function to use when you're stuck, but use it wisely as it may hurt your score. Additionally, there are statistics to keep track of your progress and leaderboards on Google Play.
