Joker Ra: Sunrise Slot by Endorphina

Two bonuses run here, and they work nothing alike, so it's worth keeping them straight. Three SCATTER symbols open Free Games, 8 spins played at the triggering bet, and the twist is what happens to the reels: every low symbol gets stripped out, leaving only the premiums plus the wild, scatter and bonus coins. So every spin during the round draws from a stacked deck of high-value icons. It retriggers if more scatters land. That's the simpler of the two.

The Sunrise Bonus Game is the real engine, and it needs 6 or more BONUS coins to fire. The grid turns into a 5x4 board of hold-and-win respins. You get 3 attempts, every empty spin burns one, but any coin landing resets the counter back to 3, so a busy board keeps going. High Sun coins carry total-bet multipliers from x1 up to x16. Solar Eclipse coins are the interesting ones: each hides a guaranteed jackpot, MIN at 20x, MID 50x or MAX 150x, revealed only when the round closes. The two coins stack on the reels. The big one is collecting 20 BONUS symbols, or covering the whole grid, which awards the ULTRA at 5000x, and that single prize is where the max win comes from. No free spins beyond the scatter round, no buy feature, no shortcut into either bonus; both have to come organically off the base game, which is Endorphina's usual house rule.

Worth knowing the wild only lands on reels 2, 3 and 4, never the outer two, substitutes for everything except scatter and bonus, and shows up stacked. Any standard line win can also be pushed into the Risk Game, a card double-or-nothing repeatable up to ten times, though jackpot money is locked out of it. Above all of this sits a separate network Progressive Mystery jackpot on three levels, drawn at random with bigger bets shortening the odds. The board itself plays out at golden hour, an amber and turquoise ancient-Egypt setting with the reels sitting against an orange sunrise sky full of pyramids and palm silhouettes, a gold Tutankhamun mask, the Eye of Ra, Anubis and a blue scarab among the icons, and the four jackpot plaques stacked down the left edge.
