Big Thunder MegaLoot Game Features

The core appeal of Big Thunder MegaLoot is its multiple, powerful slot features:

Big Thunder MegaLoot Wild Symbol Feature

Wild symbols substitute for all symbols except scatters. Watch to see if fortune rewards you with one of these symbols in the right position to help you complete a winning combination.

Big Thunder MegaLoot Gorilla Loot Features

Three different colored banana bunch symbols can land on the reels, each of which triggers a different Loot feature. If you land a mix of banana bunch symbols at the same time, the Loot features will combine. Each of these features, or combination of features, starts with eight spins. Here’s what you can expect from each bunch of bananas when they appear:

Big Thunder MegaLoot Premium Pay Loot Feature

The Green Banana Bunch activates this feature and causes wilds to substitute for all symbols. The gorilla will also appear and add Premium Pay symbols to the slot reels at random.

Big Thunder MegaLoot Premium Bonus Loot Feature

The Yellow Banana Bunch symbols trigger the Bonus Loot feature. During this feature, wild symbols will substitute for all symbols except the Yellow Banana symbols. Yellow Bananas that land on the reels will appear with MINI, MINOR, MAXI, MAJOR, and GRAND on them. Collect enough of the same Yellow Bananas and you’ll receive its associated jackpot prize, and you can also win each of these prizes multiple times if you get really lucky. The gorilla randomly adds Yellow Bananas to the reels throughout the feature.

Big Thunder MegaLoot Premium Cash Loot Feature

The Red Banana Bunch causes Red Bananas to appear on the reels with rewards of 1-75 credits that are multiplied by 50x the bet line value. The wild symbol can also substitute for all symbols except the Red Bananas while this feature is active.

Big Thunder MegaLoot awards bonus payouts and jackpot rewards during its features. Instant prize symbols deliver multipliers up to 75x your bet-per-line value. Jackpot prizes are the MINI (pays 4x your wager), MINOR (pays 10.66x), MAXI (pays 20x), MAJOR (pays 266.66x), and GRAND (pays 2,000x).

How To Win the Big Thunder MegaLoot Slot
