Demo has 20 puzzles:
- 12 basic tutorial levels
- 13-15 are easy ones
- 16-18 are a bit more complex
- 19 is hard and 20 is the most challenging out of those
Also after 1-12 levels are completed you can try playing one of the 3 random layouts. Random levels are similar to puzzles with a couple of exceptions:
- the color of launching disc is random (current and next colors are shown)
- if after 4 moves no discs dissapear, 5 more discs will spawn
The Grid: Disc Merger runs on Android 3.0+. If you want to try it - grab apk here. Any feedback is highly appreciated!
