If you play a coin or two, you can be sure that Magic Slots has a 6.3% edge, and if you play three coins, you can determine 4.3% and it should work at all Playtech casinos. The poster 'thelawnet' from the CasinoMeister and Vegas of Vegas message boards has looked at these numbers and thought the two coin images were misleading. On average, playing 2 coins on the value of all play bonuses should result in a 4.3% house edge, but this value is entirely dependent on the size of the jackpot.
