Each reel except the middle one has four Diamond Sockets above it. The game will start with 2 sockets full on each stake. Diamond Scatters that land on a reel will fill its Diamond Sockets. When all sockets are filled the respective reel will turn into a Diamond Reel which contains only locked Mystery Stones. These Mystery Stones reveal a random identical symbol on the next spin and on each spin after that until they participate in a win.

A non-paying symbol that can land on all reels except the middle one. The White Diamond Scatters increase the progress bar of the reel they appeared on by one socket. Multiple White Diamond Scatters can land on the same reel and on top of Mystery Stones and Super Wilds. White Diamond Scatters that go above the maximum sockets will instead increase the Reel Multiplier by one for each White Diamond Scatter that overfills it.

A non-paying symbol that can land only on the middle reel. It instantly fills all Diamond Sockets on all reels. If all sockets of a certain reel were already filled, it will instead increase its Reel Multiplier by one.

When a Diamond Reel is activated, it will be filled with Mystery Stones which stay locked for the subsequent spins. On each spin, all Mystery Stones will reveal a random identical symbol. If the revealed symbols participate in a win line, the Mystery Stones will unlock and leave the screen and the progress will reset to zero.

Substitutes for all paying symbols. A 1x4 Wild symbol that can only appear from Mystery Stones. If the Mystery Stones reveal four small Wild symbols, they will merge into one big Wild which will replace the Mystery Stones until it participates in a win line.

Every Diamond Scatter that appears on an active Diamond Reel will add to the Reel Multiplier. It applies to all lines in which symbols from that reel participate. If symbols from several Diamond Reels with an active multiplier participate in a line, the multipliers will multiply each other up to 96x.
