Fun concept, poor experience
Intrusive ads, and no way to pay to remove them. First ad I was shown claimed my device was infected by malware and was at risk and faked a system pop up. About 50% of the puzzles require extremely USA-centric cultural knowledge (like the names of US sport teams, US airlines, US chocolate bar brands, US WNBA teams, US NBA players, US slang, etc) Which is a shame, because the core game concept is really fun.
