▮How It Plays

One Line, One Answer

Draw a single line from the entry to the exit. Every number you cross counts; every operator changes how the next ones count.

128 Hand-Made Puzzles

Eight packs from tutorial to insane. Walls block you, bridges can be crossed twice, teleporters send you across the grid.

A New Daily Every Day

Sixteen generated levels, easy to hard, identical for everyone. Progress resets at midnight; come back tomorrow.

16 Themes

From neon to pastel. Pick the palette that keeps you focused.

Portrait Or Landscape

Phone in one hand or a wide desktop window, the layout adapts.

No Ads, No Accounts

Nothing to sign up for, nothing tracking you. Just maths.

▮How To Play

Find the targetEach grid shows the number you must land on exactly. Nothing else counts as a win.
Start at the entryPress the highlighted start tile and drag — or just use the arrow keys. The line follows you through neighbouring tiles.
Pick up numbers and operatorsCrossing a number applies it with whatever operator you crossed last. The running total is always on screen.
One unbroken lineNo diagonals, no crossing your own path, no visiting a tile twice — except bridges, which take two passes.
Reach the exit on the targetLand on the exit with the total equal to the target and the level is cleared. Otherwise back up and re-route.

	Touch	Mouse	Keyboard
Draw the line	drag from tile to tile	click and drag	`← ↑ → ↓ or W A S D`
Undo one step	drag back one tile	drag back one tile	`Backspace`
Clear the path	drag back to the entry	drag back to the entry	`R`
Pause menu	pause button	pause button	`Esc`

The line is the order of operations: 2 + 3 × 4 read along the path is 20, not 14. Backing up costs nothing, so try a route and see where it lands.

On a keyboard the arrows or WASD walk the line one tile at a time, or hold one down to run along a row — pressing back towards the tile you came from rubs that step out, so you can re-route without lifting a finger. On a teleporter any direction takes the jump. Backspace undoes one step, R clears the whole path, and Esc opens the pause menu and closes it again.

▮Gameplay Elements

The eight packs introduce these one at a time, so nothing lands on you all at once. In the diagrams, the cyan line is the path you draw.

NumberApplied to your running total with the last operator you crossed.
Add / SubtractThe first two packs. Sets how the next number counts.
Multiply / DivideDivisions come out whole — if yours does not, it is the wrong route.
PowerRaises the total. Small numbers get big fast.
FactorialApplies to the total on the spot. No number needed after it.
TargetThe number to finish on, shown above the grid. Over or under is a miss.
Entry & ExitThe line must start on the ▶ tile and finish on the ⚑ tile.
WallImpassable. The line has to go around, which is usually the whole puzzle.
BridgeThe one tile you may cross twice — once each way, never doubling back along the same direction.
TeleporterEnter one and the line continues out of its twin, anywhere on the grid.

▮The Daily Grid

Every day at midnight the game deals a brand-new set of sixteen levels. The first ones are a warm-up; the last ones will make you think. Everyone in the world gets the same grid, so compare notes with a friend.

Your Daily progress lives for the day, then the slate is wiped clean. Your progress in the regular packs is never touched.
