gates of olympus paid different than the paytable showed or maybe im reading it wrong

Had the strangest thing just now playing Gates of Olympus. Hit a line I swear should've paid more according to the paytable but the credits didn't match up at all. I checked like three times, counting up the symbols and everything. Not sure if I missed something with multipliers or maybe it's only certain combos that count for the higher pays? It wasn't a free spin round or anything weird, just the base game.

Honestly, I try to keep things simple and stick to the numbers, but when the numbers look off I get a bit paranoid. I know there's always weird little slot quirks, but have any of you seen payouts not match what the table shows, or maybe there's a trick to reading it I don’t know yet?
