🧾 What Is Action Boost SpinUP™ Gladiator?

Action Boost SpinUP™ Gladiator is a 5x4 video slot with up to 40 paylines, set in a Roman-inspired battle arena. The theme leans into gladiator glory with weapons, armor, and gold coin bonuses at every turn. Built around the Flag Spin mechanic, the game introduces a dynamic coin collection system that builds toward custom free spins, each tailored to how you’ve played.

🎮 Base Game Features

Wins are formed from left to right on 20 paylines by default (up to 40 in bonus rounds). Symbols include classic A–10 royals, weapons, gladiator helmets, and special bonus coins. Wilds substitute for all regular symbols and can appear stacked, especially during feature rounds.

Every spin offers a chance to land Gold Helmet Coins or Colored Bonus Coins, which contribute to triggering the game’s powerful Flag Spin Feature.

No traditional Scatters here—your path to bonus rounds is forged through steady coin collection and timely upgrades.

🏁 Flag Spin Feature – Core Mechanic

This is the engine that drives the game.

💡 How It Works:

  • Gold Helmet Coins are collected above the reels.
  • Once enough coins are gathered, the Flag Spin triggers.
  • One guaranteed spin activates all visible flags on the screen.
  • Landing Green, Red, Purple, or Multiple Coins on active flags determines which Action Boost SpinUP™ Free Spins you receive.
  • Coins can be basic or come with single/double upgrades, which enhance your rewards.

This mechanic turns every spin into progress. It’s visible, trackable, and keeps you invested in chasing your next big bonus.
