What Is Rumble Extinction?

Rumble Extinction is a 5-reel, 3-row online slot from Games Global Studio. It features 10 fixed paylines, highlighted winning combinations, and a range of unique symbols and bonuses. The game is designed to award payouts for matching adjacent symbols along these paylines, offering dynamic gameplay combined with engaging bonus elements.

How Do Betting and Paylines Work?

Each spin requires a total bet, with options ranging from a minimum bet of £0.20 to a maximum bet of £5.00. All 10 paylines are fixed, ensuring the same number of ways to win on each spin. Paylines follow adjacent symbol patterns across the reels, and wins are counted from left to right, starting from the first reel.

How Are Payouts Calculated?

The payout depends on the specific winning combinations formed. If multiple wins occur on a single payline, only the highest win is paid out. The overall payout is the total of all winning paylines on a spin. For each symbol, only the highest winning combination is awarded. The paytable displays current payouts according to your bet amount. The displayed maximum win per spin is rounded down to reflect the closest achievable amount.

What Do Wild Symbols Do?

Wild symbols

Wild symbols may land in both the base game and the Jurassic Bonus. They can appear on any reel and substitute for all standard symbols, helping to complete winning combinations.

What Are the Dinosaur and Jumbo Dinosaur Symbols?

The Dinosaur symbol appears specifically during the Jurassic Bonus. The Jumbo Dinosaur symbol can land on the centre three reels as a 1×3, 2×3, or 3×3 sized symbol in the base game only.

Dinosaur symbol

Jumbo Dinosaur symbol

Both 1×3 and 2×3 Jumbo Dinosaur symbols may be randomly nudged to cover a full 3×3 space for bigger potential wins.

How Is the Jurassic Bonus Triggered and Played?

If the Jumbo Dinosaur symbol lands fully in view on the centre reels during the base game, the Jurassic Bonus feature is initiated.

Jurassic Bonus

The feature begins with 3 respins on special reels containing only Wilds, Dinosaur symbols, or blanks. Each position spins on its own. Wilds that land remain locked on the reels.

Splat Bar feature

Dinosaur symbols landing during this feature knock out symbols on the Splat Bar in order of their value, starting with the lowest. Whenever any Dinosaur or Wild appears, the respin counter is reset to 3. Wilds in this round can have multipliers up to x5.

When no respins are left, one Jurassic Spin occurs, spinning with all locked Wilds and the remaining Splat Bar symbols. After the Jurassic Spin, all wins are calculated. If multiple multiplier Wilds appear on a winning payline, their multipliers are combined and applied to that win. Wilds can substitute for all symbols in the Jurassic Spin.

What Is the Bone Symbol and How Does the Bone Pile Work?

Bone symbol

The Bone symbol may appear on any reel in the base game. Landing this symbol builds up the Bone Pile, and each additional Bone symbol adds another layer to it. The Bone Pile may randomly collect up to 3 Coins above each reel, and is only active in the base game. The state of the Bone Pile is saved separately for every bet amount.

What Is the Eruption Symbol and What Happens When It Lands?

Eruption symbol

The Eruption symbol can land on any reel in the base game and triggers the Eruption feature. When activated, the Eruption breaks apart the Bone Pile and any Coins that it has captured drop onto the reels. If the Bone Pile was empty, 3 to 7 Wild symbols are awarded instead. After breaking the Bone Pile, the Eruption symbol turns into a Wild. The Eruption always lands at the same time as the Collect symbol.

How Does the Meteor Shower Feature Work?

Meteor Shower

Meteor Shower may start at random at the beginning of a spin. In the base game, this event adds Coins to the Bone Pile. If Free Spins are active, Meteor Shower puts Coins onto the centre three reels. The Collect symbol does not appear during Meteor Shower.

What Is the Collect Bonus?

Collect Bonus

Each Coin symbol that appears, either in the base game or during Free Spins, displays a cash value.

Collect symbol on reel 5

The Collect symbol can only land on reel 5. When it appears, all visible coin values are collected and awarded. This Collect Feature is available in both the base game and Free Spins.

What Is the +1 Coin Symbol?

+1 Coin

The +1 Coin symbol increases the Dinosaur Coin Multiplier by one, up to a maximum of x5. This multiplier boosts all wins from the Collect Feature, then resets to x1 after use. The +1 Coin may land during both the base game and Free Spins, and the multiplier’s value is saved per bet size.

How Do Free Spins Work?

Free Spins symbol

Free Spins symbols may land on reels 1, 3, and 5 in the base game. Landing 3 Free Spins symbols awards 8 Free Spins. During Free Spins, the centre three reels merge to form a large 3×3 Jumbo Block, which can display Jumbo symbols measuring 1×3, 2×3, or 3×3. Any standard symbol in Free Spins can become a Jumbo symbol. Jumbo symbols split into single symbols to determine payouts. All paylines and bet values remain the same as the spin which triggered the feature. Winnings from Free Spins are added to base game payouts.

What Is the Pot Bonus?

Pot Bonus

Pot prizes

If a Lava symbol lands on both reel 1 and reel 5 (in either the base game or Free Spins), the Pot Bonus feature is triggered. One Pot prize is randomly awarded, with possible outcomes being MINI, MINOR, MAJOR, or GRAND.

Is There Additional Important Information?

Some options or features may not be available in this game. If a malfunction occurs, all pays and plays are void. Any updates to game rules are made in line with regulatory requirements. Should you become disconnected, the game will display the last state played and update your balance accordingly. Results from the previous round are always available, and if a feature was in progress at the time of disconnection, it can be continued upon return.

Where Can I Find Information About the Return to Player (RTP)?

The return to player (RTP) is a theoretical estimate of long-term payout, reflecting the expected proportion of money paid back over time. The RTP value is shown in-game. It is calculated through simulations of many rounds and does not fluctuate within the game. Trigger probabilities for certain game features may vary depending on gameplay progression.
