As with most of Play’n GO’s grid games, there are a few different aspects at play during the base game on this slot. First, is the placement of wilds. At the start of every spin, up to 6 wilds are hidden underneath symbols on the grid, highlighted in gold so players know where they want their wins to fall. If a win is formed using the symbol on top of one of these wilds, when the symbol is removed the wild appears, which can have a multiplier attached. Wilds can have a x2, x3, x4, x5, x7 or x10 multiplier attached at random, or can just be single, non multiplying wilds. It is worth noting that if a win is formed using two of these multiplying wilds, only the highest multiplier is applied to the win. However, even though only the highest multiplier from the multiplying wild selection is applied, it is multiplied together with any multiplier that has been provided by the pyramid charger.
The second feature at play during this slot is the pyramid feature, on the right hand side. This is a common mechanic in Play’n GO grid games, and is something we can vaguely recognise from Reactoonz, Tome of Madness, Honey Rush or Wild Frames, each of which require players to achieve wins which build a meter. Of course, in these previous slots the meter is what eventually leads to the bonus, which is not the case within Golden Osiris. This time, the pyramid meter is used to enhance the base feature, as 3 scatters trigger the free spins feature. 25 winning symbols charge the pyramid, where one symbol is chosen at random to expand, turning adjacent symbols into this chosen symbol to trigger more wins. The pyramid feature can be re-triggered, with the first retrigger awarding a x3 multiplier to any subsequent wins, and every re-trigger thereafter increasing by x3, up to x30.
Finally, the base game of Golden Osiris offers players a “Second Chance: Scatter Explosion”, which is activated if 2 scatter symbols are in view on the grid at the end of a spin. When this is activated, any adjacent symbols to the scatter symbol are destroyed and removed from the grid, giving another chance for the third scatter symbol to land. This feature can activate once per spin, but is not applied during the free spins feature. To add to the appeal of this feature, it also provides a second chance to charge the pyramid, as the spin will be over and no winning combinations will be left when the Second Chance: Scatter Explosion is awarded.
