Sun of Egypt 3 runs four distinct special-symbol classes, and most reviews blur them into two. Keeping them straight is the difference between understanding the game and guessing at it.
1. Wild, the Mask of Tutankhamun. Substitutes for every pay symbol on the reels except the Scatter and the Sun bonus symbols. It also carries its own paytable value and is the top line-pay symbol at 12× for five of a kind. The Wild cannot help you trigger either bonus.
2. Scatter, the Pot of Gold. Pays 2× the total bet and awards 8 free spins when 3 or more land anywhere in view. Scatter symbols keep working inside the feature: landing 3 more during free spins retriggers the round for another 8 spins.
3. Bonus, the Blazing Sun. This is the Hold & Win trigger. Each Blazing Sun carries a cash value printed on it. Land 6 or more in a single spin and the respin bonus begins. These bonus symbols do not pay on lines. They pay by being collected.
4. Super Bonus, the Dark or Super Sun. Landing at least 5 regular Blazing Suns plus 1 Super Sun launches the Super version of the bonus game, in which every Sun symbol that lands is upgraded to a higher-value Super Sun. Same structure, larger denominations.
5. Mystery, the Gold & Red Sun. Appears only during bonus rounds. It sits on the grid concealed and is revealed one at a time at the end of the round, turning into either a cash value or one of the jackpot symbols: Mini, Minor, Major, Grand or Super. Mystery symbols are the mechanism by which most jackpots are actually awarded.
