About this game

CodeTrail is a puzzle game that teaches the first ideas of programming without a single line of code. A hero stands on a grid; you build a program out of command cards, press Run and watch the hero walk the trail to the goal.

Six difficulty levels, one new idea at a time:
• Arrows - up, down, left, right
• Longer paths - plan ahead
• Turns - "forward 3", "turn left", "turn right": think from the hero's point of view
• Jumps - hop over obstacles
• Loops - "repeat 3 times" instead of the same cards again and again
• Blocks - name a group of cards once, use it anywhere

Two ways to play:
• Build the path - pick the cards that bring the hero home
• Guess the finish - read a program and tap where the hero will stop

Every level is generated, so the puzzles never run out, and every level is guaranteed solvable. Shorter programs earn more stars; stars unlock new heroes: turtle, penguin, fox, bear and the red panda. Six worlds to explore: islands, forest, space, ice, city and lava.

Made for children and for the grown-ups who play along:
• No ads, no purchases, no accounts, no internet needed
• Several profiles on one device, progress is saved automatically
• Hints that point at the next card when a level gets tricky
• Gentle sounds and animations, switchable in Settings
• English, Danish, Romanian, Russian and Ukrainian

Designed for tablets in landscape; also runs on phones.
