Unsolvable level(s) – Rune Gems - Block n Tile Crush Review

Levels up to 4-12 can be solved without using the supplied or purchased cheat icons. 4-13 appears to be unsolvable without employing them. I cannot say every possible supplied 4-13 screen is not solvable but I can say many are. I assume this is deliberate to force use and purchase of these icons. So the game is less about skill as one reaches 4-13. It seems to me all levels should be solvable but with increasing difficulty. Anyway it's a challenging game but this unsolvable scheme makes it much less compelling.
