Desk research from the maker's own pages. Not yet tried by us. Checked 2026-10-24.
A free series of eight short browser games that teach programming with blocks, then nudge kids toward real JavaScript. Puzzle teaches how blocks fit, Maze teaches loops and conditions, Bird and Turtle go deeper on logic and loops, Movie and Music cover math and functions, and Pond lets kids program a duck to battle others in blocks or JavaScript. No sign-up, and it can be downloaded to use offline.
Our take: A quick, free warm-up for kids about 8-14 before Scratch or Python; not a full course.
Checked in a browser
A browser check on 2026-10-25: what loads, the ads and trackers we saw, and what a child meets first. Not a hands-on test.
| Child safety: 5 out of 5 | No ads, no chat, no links to outside sites. |
|---|---|
| Data: 5 out of 5 | No third-party hosts were contacted and no cookies were set. |
| Ease: 4 out of 5 | Big round icons for each game (Puzzle, Maze, Bird and more), though some icons and labels overlap on a phone. |
| Cost honesty: 5 out of 5 | Free and open source; no price shown. |
What we found
- 0 third-party hosts and 0 cookies.
- 0 ad frames and no links out.
- On a phone-width screen the Music, Pond Tutor, Movie and Bird icons overlap each other.
From the test: Completely clean: no ads, no trackers, no cookies, and a clear path of coding games.
