Zeus, the six-by-five field, and a slot with no lines at all
Gates of Olympus sits you on a cloud-wrapped mountaintop with a colossal, sour-faced Zeus standing to the right of the reels, arms folded, watching you lose. The board is six columns by five rows and it is filled with gemstones in graded colours, plus a chalice, a ring, an hourglass and a crown at the premium end. Like the studio’s other scatter-pays designs it has no paylines. Eight or more matching symbols showing anywhere at once is a win, wherever they happen to sit.
Winning symbols are removed, the survivors drop into the holes, new symbols fall from above, and the board re-evaluates. That tumble loop is the engine, and it runs until a board arrives that pays nothing. So far this sounds like a reskin of every other scatter-pays grid, and if you only read the rules you would be forgiven for filing it that way. It is not a reskin, and the difference has a specific name: the multiplier orb. Everything interesting about Gates of Olympus, everything that gives it a personality distinct from its stablemates, follows from the fact that Zeus can throw a glowing sphere onto a finished tumble sequence in the base game as well as in free spins. That one design decision changes what the base game is for.
