Otta’s Bloomworks is a programming puzzle game with 100 levels, 50 capstone challenges and 149 playable arrangements. Build visual programs with nested loops, if/else decisions, reusable routines, counters and robot-to-robot signals. A gentle introduction grows into demanding problems in abstraction, memory and coordination.
Try the first 5 levels free. One Full Garden purchase unlocks campaign levels 6–100. No subscription. The previews include paid campaign levels and the free advanced sample.
Curious about the deeper puzzles? Open A walk in the garden and choose Try an advanced puzzle, below My greenhouse. This free, editable sample uses conditions, counters and repeat-until across four arrangements. No purchase or campaign progress is required.
ONE PROGRAM, CHANGING CONDITIONS
In 21 puzzles, your program must solve multiple arrangements without edits between runs. Sense which beds need water, remember what you found and adapt your route. A solution that works on the first arrangement can still fail the next.
THINK IN LOOPS, ROUTINES AND STATE
Compress a winding route with nested repeats. Define a routine once and call it wherever the same job appears. Use if/else and repeat-until blocks to respond to the garden. Update counters to retain observations and decide when to stop. Previously learned blocks remain available as new concepts arrive.
TWO ROBOTS, ONE COORDINATED PLAN
Write separate programs for Tillo and Otta. Send a signal when a job is ready; make the other robot wait before proceeding. Hold a pressure plate while a teammate crosses, then release it safely. Later puzzles combine planting, delivery, irrigation, memory and coordination in a single solution.
SOLVE IT, THEN OPTIMIZE IT
Completing a route is only part of the problem. Your program must finish with every objective satisfied, across every required arrangement. Earn a star by solving independently within the level’s block budget. Find a working algorithm, then make it more compact.
BUILD, WATCH, REWIND
Drag commands into your program and nest them inside containers. Run at 1× or 2×, step through one beat, or rewind to inspect an earlier state. Watch the robots and garden respond to the instructions you wrote. No typing or prior programming experience is needed to begin.
A CAMPAIGN THAT ASKS MORE OF YOU
Explore 11 garden areas with branching paths after the first five levels. Each ten-level chapter ends with five capstones that combine its ideas. Choose among available puzzles, meet courtyard prerequisites and carry your growing toolkit into the next area. Stars are optional for progression.
GROW WHAT YOU EARN
Each completed level unlocks a flower; an independently earned star unlocks its gilded version. Arrange unlimited copies of unlocked flowers in My greenhouse, your own 20-by-20 garden. Pursue 28 achievements, including 10 hidden discoveries and the challenge of earning gold across all 100 levels.
HELP WITHOUT SKIPPING THE THINKING
Hints are free. Earn solution credits through independent play and spend one to reveal a program; credits are never sold. Assisted completions earn regular flowers. Stars, gilded flowers and programming-skill achievements require independent attempts.
Play on iPhone or iPad with expressive robots, miniature gardens and mellow music. Game Center is optional for achievements. Level progress and greenhouse designs are saved on your device.
