Log Puzzle the demo is better and has more levels than most $1 Rush Hour games. Log Puzzle demo has 250 puzzles (50 puzzles each for Easy, Medium, Hard, Advanced, and Extreme). For the average joe this is enough to get a full gaming experience. Blocked $1 has 100 for instance and Parking Lot (not in appstore at the moment) has 350. Sure they want you to buy the full version of Log Puzzle $1 which has 1,950 levels but just suprised how everyone goes Lady Gaga over Blocked and not a single mention of a FREE game which has 2.5 times more puzzles. Boggles my mind but then again we are talking about the masses here. Anyway my favorite $1 Rush Hour ones are Block Hints $1 22,850 levels and Blue Block $1 39,963 levels.
