Sum Square is a minimalist educational puzzle game that challenges your arithmetic and logic skills. In this browser-based game, you use your mouse to drag numbered tiles into colored boxes.
The objective is to arrange the tiles so that the sum of the numbers within each box perfectly matches its target value, making it a great brain-teaser for players of all ages.
The core concept is straightforward but requires careful thought. Each level presents you with a set of numbered tiles at the bottom of the screen and several colored boxes, each displaying a target number.
Your task is to place every single tile into the boxes to satisfy all the target sums simultaneously.
You must use each tile exactly once. The challenge comes from figuring out the correct combination of tiles for each box, especially as the puzzles grow in complexity. It's a game of calculation and logical deduction.
Sum Square starts with simple addition puzzles that serve as a gentle introduction. As you progress, the levels become significantly more demanding. You'll encounter a greater number of tiles and boxes, forcing you to manage more variables at once.
Later stages may also introduce negative numbers, which adds another layer of complexity to your calculations. Success in these advanced puzzles requires not just quick math but also strategic planning and the ability to see several steps ahead, much like in games such as Sudoku.
You can play Sum Square completely free directly in your web browser. There's no need for any downloads or installations, so you can start playing instantly.
Because it's a simple HTML5 game, it runs on most devices and isn't blocked by school or work networks, making it a perfect choice for a quick mental workout during a break.
The goal in Sum Square is to correctly place all the numbered tiles into the colored boxes. To complete a level, the sum of the numbers inside each box must equal the target number shown on that box.
Controls are simple and intuitive. Use your mouse to left click and hold on a numbered tile from the bottom tray. Drag the tile and release the click to drop it into any of the colored boxes on the screen.
If you make a mistake or want to try a different combination, you can click and drag a tile out of a box at any time. Move it to another box or return it to the bottom tray.

Start with Large Numbers - Try to place the largest numbered tiles first. They have fewer possible combinations and can help narrow down your options for the other boxes.
Look for Exact Matches - Quickly scan the puzzle to see if any single tile's value matches a box's target number. Placing these obvious fits first simplifies the rest of the board.
Work Backwards - If you're stuck, pick a box and think about which available tiles could add up to its target. This can be more effective than randomly placing tiles.
Use Process of Elimination - Every tile you place correctly is one less variable to worry about. This makes it much easier to figure out where the remaining tiles must go.
Check Your Work - Before moving on, do a quick mental check to confirm the sum in each box is correct. It's easy to make a small calculation error.
