Sword of Destiny Slot by Light & Wonder

The base game runs four random features, and any spin can fire one of them. Whichever lands does the same structural trick first: the screen physically grows. Two extra rows drop into place, the 5x4 board becomes 5x6, and an extra 25 paylines unlock for that single spin, so you're suddenly paid across 50 lines instead of 25. What changes is the flavour. Clumped Wilds fills 1, 2 or 3 entire reels with stacked Wild. Random Wilds scatters 4 to 9 single Wild positions across the larger grid. Picture Wilds drops a connected blob of 4 to 10 adjacent Wilds together in one area. Symbols Upgraded picks two or more of the four card-style icons (flask, gauntlet, scroll, necklace) and morphs every copy into a Sword Man, Sword Lady or Castle premium. Only one fires at a time, and none of them can fire on a spin that also triggers either bonus.

The Free Games Bonus comes from three XZONE scatters on reels two, three and four. It pays 2x your stake on the trigger and hands you 8 spins, with the catch sitting above the reels: a row of per-line multipliers between 2x and 10x, displayed openly, and applied to each winning line on its own. Two different paylines on the same spin can score under two different multipliers. After every winning spin those numbers can shift around, so the value of any single line is moving while you watch. Any XZONE that lands during the round adds one extra spin to whatever you have left, with no reset.

Three BONUS coins on reels one, three and five open the Temple Tower Jackpot Feature, a 16-step ladder pick-bonus with cash prizes on the lower rungs and three fixed jackpots at the top: MINI at 25x, MAJOR at 125x, GRAND at 625x total bet. Twenty coins sit in four rows of five, you get three picks, and each one bumps you 1 to 6 steps up the ladder. The prize at the highest rung you reach after the third pick is what you walk away with, so the ceiling depends entirely on how generous those three jumps are. Above the reels an animated panel cycles through three portraits, a winged warrior king on a flaming throne, a barbarian queen by candlelight, a dark-haired armoured swordswoman with her henchmen behind her, against a moonlit gothic castle backdrop in deep blue, gold and crimson. This is an older Bally/SG Interactive cabinet still running on the SG Digital Casinarena GLS engine, no feature buy, no ante bet, the four random features carrying the base game while the two bonuses do the heavy lifting.
