Not all levels are winnable without purchases – Rune Gems - Block n Tile Crush Review
This is a fun and challenging game but you cannot get through some levels without buying special "magic" or "time" runes. I bought the extra level pack but now am dead on level 7-9. Seems to me if you buy the extra levels they should include some extra runes. Games that make you pay pay pay drive me nuts.
