Golden Osiris review
The legend behind Golden Osiris says the god turned sunbeams into solid gold and used them to build a tomb, then hid it from mortals. Play'n GO's 2020 slot turns that into a rule: wilds sit hidden under symbols, and a Pyramid charges as you win. When it opens, it picks a symbol and spreads it across neighbouring ones. Free spins start with the Pyramid already full.
Hidden wilds
Wilds are placed underneath highlighted symbols and are uncovered when those symbols are part of a winning combination. A hidden wild can carry a multiplier of x2, x3, x4, x5, x7 or x10. When a win includes more than one multiplier, only the highest applies. On each new cascade, up to six wilds are added beneath the grid.
That last rule means a long cascade chain keeps feeding the board with fresh hidden wilds, even though each one still has to be uncovered by a win.
The Pyramid
The Pyramid is the centre of the design. It charges with 25 winning symbols, wilds included. Once it is charged, all wins are counted and it opens to reveal a chosen symbol.
Symbol conversion
Any instance of the chosen symbol randomly converts an adjacent symbol into the chosen symbol, including clusters of up to four. This creates new matching symbols next to the originals.
Recharging and multiplier
The Pyramid can be recharged. Its first re-trigger applies a symbol Expansion Win Multiplier of x3, and later re-triggers continue to raise it, up to x30.
Second Chance Scatter Explosion
If two Scatters are on the grid at the end of a spin, the symbols around them are destroyed to give the third Scatter a chance to land. It activates once per round and never during the free spins.
Free spins
Three Scatters trigger five free spins, and three more Scatters during the round add five more. The Pyramid starts fully charged on every free spin and opens when all wins are counted. In this round it chooses from the Bird, Cat, Ankh, Jackal and Scarab symbols.
The studio says you can win up to x12000 the bet in the free spins round. Our catalogue does not publish a max win for the game, so this is the studio's claim and should be read as the top of the bonus, not as a verified ceiling.
Maths
Golden Osiris lists five RTP versions, led by 96.27% and ending at 84.27%. Their house edges run from 3.73% to 15.73%, which is $37.30 to $157.30 per $1,000 wagered. The other versions are 94.25%, 91.25% and 87.27%. Volatility is High.
In a 100-spin session at $0.20, the average cost is $0.75 on the best version and $3.15 on the weakest. At $1 it is $3.73 against $15.73, and at $5 it is $18.65 against $78.65.
Other 2020 releases
Octopus Treasure lists 96.26%, Blinged and New Year Riches 96.25%, Cat Wilde and the Doom of Dead 96.29%, Saxon 96.24% and Charlie Chance in Hell to Pay 96.23%. All are rated High and were released in 2020.
Pros
- Hidden wilds carry multipliers up to x10, and only the highest applies to a win
- The Pyramid is rechargeable and its multiplier climbs up to x30
- Free spins begin with the Pyramid already charged
- Free official demo available
Cons
- No max win in our catalogue; the 12,000x figure comes only from studio copy
- Five RTP versions, the weakest at 84.27%
- High volatility, so the bonus carries much of the potential
Verdict
Golden Osiris is a layered cascade game: hidden wilds, a Pyramid that charges at 25 winning symbols and a re-trigger multiplier that reaches x30. At 96.27% RTP and High volatility it matches the other 2020 games listed above. The studio's 12,000x figure for the free spins is a claim, not a catalogue value. Paid play costs about $37.30 per $1,000 on the best version, so use the free demo first.
