Line up Forward, Turn Left, and Turn Right blocks, then run the program so a fox walks a floating 3D path and gathers every star. Turns happen in place. Kids practice sequencing and facing without typing code.
Look at the Path
The fox starts on one tile and faces a direction. Gold stars are the goals. Purple shades are tiles to avoid.
Build a Sequence
Tap Forward to walk one tile the way the fox is facing. Tap Left or Right to spin in place. The tray shows the program in order.
Run It
Press Run. The fox follows the blocks from left to right. Press Clear to wipe the tray and try again. Tap a tray block to remove just that step.
Gather Every Star
Land on each star. If the fox walks off the path, onto a shade, or the program ends too soon, you lose a life and edit the sequence.
Program, Then Run
Tap Forward, Left, or Right to grow a program. Tap a block in the tray to take it out. Nothing moves until you press Run.
Turns Stay in Place
Left and right spin the fox on the same tile. Forward always means the way the fox is facing — the same idea used later in Logo and Scratch.
Stars and Shades
Easy paths hold one star. Medium adds a purple shade to walk around. Hard uses two stars, so the program has to visit both.
Score, Streak, and Lives
A clean run pays 100 per star times your streak, plus a first-try bonus. Three misses close the trail. Best score is saved in the browser.
Star Trail is a first coding game on a 3D path. Players do not type. They tap visual blocks to write a sequence of moves, then run that sequence so a fox walks floating tiles. The core idea is an algorithm: an ordered list of steps that either reaches every star or does not. Turns happen in place, and Forward always means the way the fox is currently facing.
Teaches Sequencing
Kids see that order matters. Two Forwards and then a turn is not the same as a turn and then two Forwards.
Makes Facing Concrete
Left and right are relative to the fox, not the screen. That is the same idea used later in Logo, Scratch, and robot kits.
Debug by Watching
A failed run shows exactly where the path went wrong. Students change one block and try again.
Works on Touch
No drag required. Tap to add, tap to remove, tap Run. The tray is large enough for small hands.
No. Tap a command to add it to the tray. Tap a block in the tray to remove it.
No. Left and Right spin the fox on the same tile. Only Forward walks to the next tile.
A shade is a hazard. If the fox lands on that tile, the run stops, you lose a life, and you can edit the program.
Easy paths are short with one star. Medium adds a shade to walk around. Hard uses two stars and extra shades.
Kindergarten through fifth grade. Easy is a first sequencing lesson. Hard is useful once students are comfortable with left and right from the character's view.
