SudokuSmart is the perfect assistant for anyone that enjoys number puzzles. It provides guidance on almost any sudoku, offers daily warm-ups and levels, and even gives players the tools to create their own sudokus. Whether you have never seen a sudoku before, or are an expert, SudokuSmart will be of use to you. Additionally, the app places emphasis on a friendly interface and communication with players. Therefore, any suggestions, comments, or problems with the app are encouraged, as these will indefinitely play a role in future updates. Key features: Home - Complete new sudokus every day and every week; share your time of the Daily or Weekly with your friends; build up a streak, and go back to previous days to see your progress; if stuck, simply press the Help button to redirect to the Sandbox page, or tap the reveal button to show the candidates in the selected square (or hold for the entire grid). Sandbox - Enter any sudoku using the number input pad and utilise the various tools: the Help button goes step by step through the solving process for the next number, including advanced methods such as AIC; the Auto-Solve button will immediately return the solution grid (or a solution grid if there are multiple solutions); the Reveal button shows all the candidates; the Save button and Load button can be used to store and revisit any sudoku grid. Levels - 84 levels of ranging difficulty (hardest requiring AICs length 5+), with the hardest difficulty - Master - soon to come. Complete all the grids to become adept at solving sudoku, and go back to recomplete grids to see how much faster you have become. Settings - High degree of customisation within levels and for the sandbox: decide whether to embolden numbers, whether to highlight the selected row, column and/or box, whether jottings are automatically removed, and automatic square change. Additionally, you can customise the completion animation for all grids, with three to unlock if requirements based on time, difficulty, and streak are met. Advanced controls, darkmode, and similar sandbox settings can also be adjusted.
