Royal Sands Slot by HeronByte

Four free spins options. That is where the decisions happen. Pick 15 spins starting at x1, 10 spins at x5, 5 spins at x10, or roll the dice on the mystery option that gives 15 spins at x5 but randomizes which of the other three configs you actually get. The progressive multiplier climbs by one with every tumble win during the round, and it never resets between spins. So those 5 spins starting at x10 can push the multiplier into serious territory fast if tumbles chain.

For 100x your bet, the buy bonus skips straight to that choice screen. A Double Chance toggle is also available in base game for 1.25x your stake, doubling the odds of landing three scatters to trigger the round naturally. Three more scatters during free spins add extra spins with no cap on retriggers.

The base game runs on HeronByte's ULTRAWAYS engine - six reels with anywhere from 2 to 7 symbols each, pushing the way count up to 200,704 at full expansion. Wins trigger tumbles that clear winning symbols and drop new ones in, so multiple payouts from a single spin are common even outside the bonus. Warm sandstone columns frame an Egyptian riverside behind the reels, with temples and palm trees catching late afternoon light. High-pay symbols are Sphinx, Ra, Anubis, and Cleopatra, all drawn in a golden illustrative style that leans ornate without going dark.

One thing that is unusual for a Megaways-style game - there is a gamble feature. After any base game win you can double or nothing the payout. It is a small addition but it gives the base game an extra layer between bonus triggers that most variable-reel slots skip entirely.
