Number Trail

Find your way through Number Trail, a puzzle game about numbers, space, and one continuous path.

Start at 1, visit the numbered checkpoints in order, and fill every square on the board. Move horizontally or vertically without crossing your path or using a square twice. A nearby number is not always your next destination—plan ahead and leave room to finish!

20 handcrafted puzzles
Explore twenty 4×4 levels with different starting positions, spirals, detours, corner pockets, and carefully placed finishing squares. Complete each level to unlock the next.

Simple controls
Tap or drag to extend your path. The starting square is selected automatically, and Undo and Reset let you rethink a move. Play at your own pace without a countdown timer.

Progress that stays with you
Your progress is saved, and the level chooser takes you to your latest unlocked level. The portrait layout keeps the board easy to reach.

Help when you need it
The first five levels are ad-free and include free hints. From level 6, each hint costs one credit. Choose to watch a rewarded ad to earn three credits. Later levels also include banner ads and occasional ads after completing a level. Ad availability requires an internet connection.

Connect the numbers. Fill the board. Complete the trail.
