Maze game online
In this maze game online you guide the blue dot from the top-left corner to the green goal at the bottom right. Every maze has exactly one route, so it can always be solved. Pick one of four sizes (8 × 8 to 25 × 25), steer with the arrow keys, W-A-S-D or a tap, and time yourself. No sign-up, works on phones.

How it is calculated
In short: this maze game online builds a new maze every time, with exactly one route from start to goal. You steer the dot with the arrow keys or by tapping and try to get there quickly without running into too many dead ends.
The four sizes
| Level | Grid | Squares |
|---|---|---|
| Easy | 8 × 8 | 64 |
| Medium | 12 × 12 | 144 |
| Hard | 18 × 18 | 324 |
| Expert | 25 × 25 | 625 |
How to get through faster
- Wall follower: keep one hand on the left wall in your mind and follow it. Because these mazes have no loops, the rule always reaches the goal.
- Think backwards: the goal is often easier to reach from the end. Trace the route from the green square back with your eyes.
- Spot dead ends: a corridor without a side branch that ends at a wall is a dead end. The light-blue trail shows where you have been.
How the mazes are made
The computer builds them with a depth-first search: starting in the corner it walks to a random unvisited neighbour and knocks down the wall in between, until every square has been reached. The result has no loops and no unreachable squares – between any two squares there is exactly one route.
Puzzle series
“Next puzzle” takes you through a numbered series. The number and the size define the maze exactly: open no. 12 on “Medium” and you get the same maze as everyone else. Your progress stays on your device only.
Frequently asked questions
Does every maze have a way to the goal?
Yes. Every maze here has exactly one route from start to goal. There are no loops and no cut-off areas.
What is the fastest way to solve a maze?
Always follow the left wall or always the right wall with your hand. In mazes without loops this is guaranteed to reach the goal. It is faster still to trace the route backwards from the goal with your eyes.
How do I steer on a phone?
With the direction buttons below the maze or by tapping an adjacent square. On a computer the arrow keys or W, A, S and D are enough.
What does “Show solution path” do?
It shows the shortest route from your current position to the goal. If you use it, that maze does not count towards the puzzle series.
