Monkeys Gold xPays

Monkeys Gold xPays by No Limit City is a video slot played on a 6×6 grid where traditional paylines are replaced by the xPays mechanic. Instead of fixed lines, wins occur when three or more matching symbols land adjacent on the first three reels; non-winning symbols disappear, winning symbols drop to the bottom, and new symbols cascade in until no further wins appear. Colossal Symbols can appear as 2×2 or 3×3 blocks, each carrying multipliers up to 500×; empty spaces beneath these colossal symbols are filled by wilds. There is a Symbol Upgrade feature: whenever a full horizontal row is filled with symbols, all collected symbols upgrade to a higher-paying symbol; if that row is already made of the highest symbol, it gains a symbol multiplier instead. Symbols themselves can carry multipliers, which causes them to count as multiple symbols when forming winning combinations; wilds inherit these multipliers when substituting. The Free Spins feature is triggered by landing three bonus symbols (scatter-like); this gives ten free spins, with extra bonus symbols adding three more spins each. At the start of the Free Spins round, a dice roll determines both the starting Vine Multiplier and how many steps (x1, x2 or x3) it will increase by for each full row filled during the bonus. The Vine Multiplier is sticky: it persists and increases with each row filled throughout the free spins. Players can also choose a Bonus Buy option (NoLimit Bonus) to purchase the Free Spins feature directly for 73× their base bet, where available. The maximum win potential is up to 12,683× the bet.
