Draw the path,
fill every square.
Yolvo is a calm path puzzle: start at 1, pass the numbers in order and fill every square exactly once. No timer, no pressure.
No account · Works offline · No personal data collected
In three steps
No sign-up, no setup.
Find the start
Begin at 1 and look ahead: the last number ends the path.
Draw with your finger
Drag through neighbouring squares; drag back to shorten, lift your finger and the line stays. Undo is unlimited.
Think, do not guess
Every puzzle has a single solution. Stuck? A hint explains why the next move is right.
Calm and clear
The caterpillar path
The line passes through every square exactly once, never crosses itself and visits the numbers in order; brown walls block the way in harder puzzles.
Hints with reasons
Every puzzle includes 3 free hints that explain the logic behind the next step.
Friendly to fingers
Slanted drags snap to the nearest square and never skip one; colour-blind mode with high contrast.
Offline

Questions you might have
Do I need an account or internet?
No. Everything runs on your phone and nothing is sent anywhere.
What data does the app collect?
Yolvo collects no personal data. The free version shows non-personalised ads through Google AdMob; subscriptions are handled by Apple.
Do I need to be precise with my finger?
No. Slanted drags snap to the nearest square, and a wrong turn can be undone with one tap.
