- Game type
- Puzzle – untangle / tap-to-escape
- Goal
- Tap each worm so it crawls out of the knot. A worm only escapes if nothing blocks its path, so you have to work out the order.
- Controls we used
- Mouse click (tap on a phone). No keyboard needed.
- On a phone (390px test)
- Yes. Level 1 filled the portrait 390px screen with large, easy-to-tap worms.
- Load time
- Slow for its size: a "Loading…" screen stayed up for roughly 10–13 seconds before level 1 appeared.
- Difficulty
- Easy to understand, but mistakes are punished: each blocked tap cost one of three hearts.
- In-game ads
- Yes – GameMonetize video-ad system; after losing all hearts it offered a "Play On" button marked with an ad icon, or Retry.
- How a session plays
- Level 1 opens with a hand pointer showing the first move. The first worm slid out cleanly; our next three careless taps hit blocked worms and emptied the hearts, ending the attempt.
Our verdict: A neat 3D knot puzzle that suits touch screens. Think before each tap – three mistakes end the level.
How we test: we open the game in a desktop browser and in a 390px-wide phone view, time how long it takes to load, play through the opening level or round and note exactly what we saw. We only write down things we observed. More about our testing.
