Provider and Basic Game Details

Who developed Primal Rampage, and what are its fundamental game specifications?

Primal Rampage is a slot game from Play’n GO, featuring 3 reels. The game allows for a minimum bet of £0.10 and a maximum bet of £4.00. There are no traditional paylines; instead, wins are awarded for adjacent symbol combinations as outlined in the game’s paytable and rules.

How Are Wins Awarded?

What is the win structure in Primal Rampage?

Primal Rampage does not use traditional paylines. Wins occur when 3 adjacent symbols appear from left to right, excluding Vault Bonus and Rage Symbols. Winning combinations pay from the left-most reel to the right, and when multiple winning ways occur in a single round, all winnings are combined. Only the highest win is paid per winning symbol combination, and all prizes are paid out at the end of the round.

Symbols and Special Features

What special symbols and features can appear during gameplay?

  • Wild Symbol: The Wild can land on reel 2. It substitutes for all other symbols except Vault Bonus and Rage Symbols. Wilds may come with multipliers of X2, X3, X5, X10, X25, X50, or X100, which only apply to win combinations that include a Multiplier Wild.
  • Vault Bonus: The Vault Bonus symbol may appear on reel 2. When it lands, the Ape can smash the reels to unlock Vaults, each awarding one of the following: GRAND (X1000), MEGA (X250), MAJOR (X75), MINOR (X30), MINI (X10), X9, X8, X7, X6, X5, X4, X3, X2, or X1. The winning is calculated as the Vault multiplier times the Total Bet.
  • Rage Symbol: Rage Symbols may land on any reel in the Base Game. Collecting 3 Rage Symbols triggers the Primal Wheel. If 1 or 2 Rage Symbols are collected, the Ape stores them for a chance to trigger the Primal Wheel later.

The Primal Wheel Feature

How does the Primal Wheel function in the game?

When triggered, the Primal Wheel offers a chance to win the GRAND (X1000), MEGA (X250), MAJOR (X75), MINOR (X30), or MINI (X10) Bonus. Winning one of these awards the corresponding payout instantly, calculated as the multiplier times the Total Bet. Alternatively, the Primal Wheel can trigger either Kong Quest or King Spin Free Spins. The presentation of prizes on the Primal Wheel does not reflect their real probabilities.

Kong Quest Free Spins

What happens in the Kong Quest Free Spins feature?

Kong Quest Free Spins can only be activated through the Primal Wheel and start with 8 Free Spins. During Kong Quest, the Ape stretches the reels after every spin, resulting in random reel sets: 3×3 (27 ways), 3×4 (64 ways), 3×5 (125 ways), 3×6 (216 ways), 3×7 (343 ways), or 3×8 (512 ways). The Vault Bonus can still award the usual rewards, and may also contain an extra Free Spin. Each Vault Bonus with a Free Spin adds one more spin, up to a maximum of 30 Free Spins in this mode.

King Spin Free Spins

What is unique about the King Spin Free Spins?

King Spin Free Spins are also triggered through the Primal Wheel and award 8 Free Spins. All Vault Bonuses are instantly unlocked when landed, and the Ape can smash the reels several times to upgrade Vaults as high as the GRAND reward. In this feature, Vaults may grant special multipliers: MEGA2X (X500), MAJOR2X (X150), MINOR2X (X60), and MINI2X (X20). Other possible Vault outcomes are GRAND (X1000), MEGA (X250), MAJOR (X75), MINOR (X30), MINI (X10), and multipliers down to X1. Free Spins in King Spin are limited to 8.

How Are Bets Selected and Game Rounds Started?

What are the betting options and controls available in Primal Rampage?

Players choose their bet size using plus and minus buttons to increase or decrease the amount. The round begins by clicking the Spin button or using the Spacebar. Once the reels have stopped, any winnings or outcomes are calculated according to the paytable and added together.

Game Round Interruptions

What happens if a game round is interrupted?

If play is interrupted, all game information and any bets placed are saved until the player reopens the game, allowing continuation from where the interruption occurred. Any unresolved bets from incomplete games become void after 7 days. Accumulated collectibles or game progress are cleared after 180 days unless the player logs into a Play’n GO game within that period. Malfunctions void all pays and plays.

Additional Game Actions

What other actions can players take during play?

  • Paytable: View or hide the game’s paytable.
  • Spin / Start / Spacebar: Initiate a game round with the bet currently selected.
  • Auto Adjust Bet: If the player’s balance is too low for their current bet, this option automatically reduces the bet to the highest possible value that can be played.

Payout Information

How are payouts and the RTP handled in Primal Rampage?

All winnings from way wins, features, bonus games, and scatters (if included) are combined at the end of a game round. Free Spins are played using the same bet as the round that triggered them, unless otherwise stated in the game rules. The RTP is displayed within the game. The outcome of each round and the total winnings are determined by the symbols on the reels as per the paytable and rules.
