Unsigned Int is a fast, browser-based math puzzle that tests mental arithmetic and planning. You start with a running total and click numbered objects to apply their operations. Each object displays an operation such as +5, -3, x2, or /4. The operation on the object you click immediately changes the total. Your goal is to keep the total within the allowed range of 0 to 20 while reaching target values or clearing levels.
The game offers two play modes. Easy mode focuses on addition and subtraction to build confidence and pattern recognition. Hard mode adds multiplication and division for deeper challenge and strategy. Each level requires you to think ahead because some clicks can quickly push the total out of range. Unsigned Int appeals to players who want short, focused rounds that train math skills, improve number sense, and reward smart moves.
Unsigned Int runs in any modern browser using HTML5, so you can play on desktop, laptop, tablet, or phone without downloads. The simple controls and clear rules make it ideal for quick practice sessions, classroom warmups, or casual daily play. The game blends puzzles with core arithmetic to make learning active and engaging.
