Addition Maze - online puzzle game

overview

Addition Maze is a number path puzzle played on a grid filled with numbers. Your goal is to find a connected path from the top-left corner (Start) to the bottom-right corner (End) such that the sum of all numbers along your path equals a given target value. Each puzzle has exactly one valid solution path.

rules

• Start from the green cell (top-left) and reach the blue cell (bottom-right).
• Move only horizontally or vertically to adjacent cells (no diagonal moves).
• Each cell can only be visited once per path.
• The numbers on all visited cells must add up to exactly the target sum.
• There is exactly one correct solution path for each puzzle.

controls

• Click an adjacent cell to extend your path from the current endpoint.
• Click the last cell on your path to undo the most recent step.
• Press Check to verify if your current path is the correct solution.
• Press Hint to reveal the next cell in the solution path.
• Press New Game to generate a brand-new puzzle in the current difficulty mode.

scoring

Your performance is measured by time and move count. Fewer moves and less time indicate better pathfinding skills. Using hints adds to your hint counter. Try to solve puzzles without hints and with minimal backtracking for the best results.

tips

• Calculate the difference between the target sum and your current sum to plan ahead.
• If the remaining sum needed is too small or too large for the cells left, backtrack early.
• On larger grids, try to identify clusters of numbers that match needed sub-totals.
• The start and end cells are always included in the path. Factor their values into your planning.
