Gates of Olympus is a 6x5 pay-anywhere slot from Pragmatic Play, released in February 2021, with 96.50% RTP, medium volatility by its own rules and a 5,000x max win. Wins need 8 or more matching symbols anywhere, and multiplier orbs add up to 500x.
The grid is 6 columns by 5 rows, with no paylines. You win when 8 or more matching symbols land anywhere on the screen; they don't have to touch. The total of each symbol at the end of the spin sets the pay. In the demo the bet runs from $0.20 to $300, and a casino sets its own range in euro.
With cascading reels, winning symbols are paid and vanish, the rest drop down and new ones fall in from above. This repeats until nothing wins, with no limit, and the whole sequence is credited at the end.
Pays are multiples of your total bet, set by how many matching symbols land: 8-9, 10-11, or 12 and over.
Pays in times your total bet

Crown
The top pay: 50 times your bet for 12 or more, which is €10 on a 20 cent spin.

Hourglass
Pays half of what the crown does at 12 or more.

Ring
10 or 11 rings pay 5 times your bet.

Chalice
Pays little until you reach 12.

Red gem

Purple gem

Yellow gem

Green gem

Blue gem

Zeus (scatter)
Pays in any position: 4, 5 or 6 give 3x, 5x or 100x your bet. 4 or more start the free spins.

Multiplier orb
Worth 2x to 500x. It has no pay of its own: it multiplies your wins.
A group of 8 or 9 rarely returns your full bet: a blue gem pays 0.25 times and a yellow one half. What moves the result is big groups and the orbs.
Orbs can land on any spin or tumble and take a random value from 2x to 500x. When the sequence ends, the values of all orbs on screen are added and the sequence's total win is multiplied by that sum. That is the game's multipliers feature.
On a €1 bet, say a run of tumbles adds up to €4, and two orbs, 5x and 10x, are on screen at the end. They add to 15x, so you collect €60. Without the orbs you would get €4.
4 or more scatters anywhere on the grid award 15 free spins, according to Pragmatic Play's game page. If 3 or more land during the round, you get 5 more.
Here the multipliers stack. Each orb that lands on a winning spin joins a running total that lasts the whole round, and that total multiplies every later win where a new orb lands. On a €1 bet, a €2 win with a 5x orb pays €10. Two spins later a 10x orb joins and another €2 win pays €30, because the total is now 15x.
Where the casino offers it, bonus buy opens the free spins for 100 times your bet: €20 on a 20 cent spin, with no guarantee of winning it back. The ante bet adds 25% to each spin (25 cent instead of 20) and doubles your chance of triggering the round yourself; the buy is off while it is on. The RTP stays at 96.50% either way.
Pragmatic Play lists a 96.50% RTP: the share of stakes the game pays back over millions of spins. In one session, anything can happen. If your casino ran a version 2 points lower, you would lose about €2 more per €100 staked in the long run. The info screen shows the figure in use.
The rules screen labels the game medium volatility: it pays steadily, and the range runs from low to very high. The max win is 5,000 times the bet, €1,000 on a 20 cent spin and €5,000 on €1. A round that hits the cap ends at once.
The game draws on Greek myth: Zeus is the scatter, and crowns, hourglasses, rings, chalices and coloured gems sit on glowing discs. The multiplier orbs have wings. It is listed under Zeus, Olympus and Ancient Greece slots, in the 3D slots style.
The demo can't show your casino's RTP version or its bonus terms, and bonus buy may not be offered where you play. Demo wins can't be cashed out. Most of the big wins depend on high-value orbs, which land at random.
The versions from Pragmatic Play share the base mechanic: pay anywhere with 8 or more symbols, plus tumbles.
