Chance Machine 20 Dice Slot by Endorphina

Everything on the reels is a die. Not dice as a theme bolted onto a fruit machine, but the actual symbols, every gemstone value rendered as a glossy golden 3D cube studded with coloured jewels for pips. Amber, magenta, blue and green gem-faces climb the low-to-high values, then a red lucky 7 die and a gold lightning-bolt die take the top spots. They tumble across a board sat in a gold border on deep red velvet, the kind of opulent red-and-gold table-game look that suits the high-roller feel. It's the cube re-skin of Endorphina's Chance Machine 20, so the layout is the same gem slot underneath, just dressed entirely in dice.

The feature set is small on purpose, and that's the thing to know going in. No free games, no bonus round, no buy button. What you get is a golden crown expanding wild that only ever shows up on reels two, three and four. When it lands it stretches vertically to fill its whole reel, standing in for everything except the two scatters, so a single crown can plug a full column into a combination it would otherwise miss. Wins read left to right across the 20 fixed lines.

There are two separate scatter-pay symbols, and they work in parallel rather than triggering anything. The Mask scatter turns up on reels one, three and five; the Star scatter can land on all five. Enough of either anywhere on the grid pays directly, and that scatter win gets added on top of your line wins rather than replacing them. Only the highest win per scatter type counts on a given spin, so landing both a Mask and a Star payout in the same spin stacks two scatter wins onto your line total.

Any win can go to the Risk Game, a card gamble where you pick one of four face-down cards to beat the dealer and double up. You can push it up to ten times in a row, the joker beats everything and the dealer never draws one, though a draw just holds your win. Sitting behind all of it are three network mystery progressives, GRAND, MAJOR and MINOR, dropped at random with a bigger bet shortening the odds. Jackpot money can't be sent to the gamble, and there's no free-spins layer to wait on, so the base reels and those scatter dice are doing the work every spin.
