## Description

Give a robot a program to light up the grid! Kids learn real coding ideas — sequencing, loops, functions & debugging — by tapping command tiles. 2 players or solo.

Robo Trails turns real computer-science thinking into a friendly, tap-only puzzle — no reading or typing required. Give a cheerful robot a program made of command tiles, press Run, and watch it drive across the grid leaving a glowing trail, lighting up every star tile.

It's the ideas real programmers use, one gentle step at a time:
• SEQUENCE — put commands in the right order: Forward, turn Left/Right, and Light.
• LOOPS — a Repeat block does a pattern again and again, so you do more with fewer tiles.
• FUNCTIONS — teach the robot a mini-routine (P1/P2) and call it whenever you need it.
• DEBUG — a program that's almost right is loaded for you; find the one thing to fix.

A TILE BUDGET that grows the mindset
Every puzzle has a limited number of tiles, so kids are nudged to spot the pattern and use a loop or a function instead of brute force. Fewer tiles earns more stars — elegance, not just success.

A REAL DUEL
• Two players take turns on the SAME puzzle — a "pass the tablet, no peeking" screen keeps it fair; the faster correct program wins the round, best of three.
• Or race a friendly computer you can actually beat.

FOR FAMILIES
• Free: the whole Sequence world (solo) + all 2-Player + vs Computer, forever.
• One optional, one-time unlock adds the solo Loops, Functions & Debug challenges — behind a parental gate, no ads, no subscriptions.
• 100% offline — no accounts, no data collected.
• 11 languages with full right-to-left support.

Every puzzle is guaranteed solvable, and failures are gentle — the robot just stops, and you tweak your program and try again. Perfect for curious kids (and grown-ups) taking their first steps into coding.
