Frenzy Clusters - Demo & Slot Review

Frenzy Clusters is played on a 7-reel, 7-row grid with a cluster pays system. Wins are created by landing 4 or more matching symbols connected horizontally or vertically. When a winning cluster pays, the winning symbols disappear and new symbols fall into the empty spaces, giving the spin a chance to continue.

The RTP is 97.11%, which is very strong for a modern online slot. Volatility is high, the maximum win is 10,000x the bet, and the bet range runs from 0.20 to 25. The hit frequency is listed at around 37.87%, while the Free Spins frequency is around 0.37%.

At the start of the game, players can choose one of 5 heroes. The gameplay itself is driven by cluster wins, locked cells, special symbols, Free Spins, Mega Free Spins, progressive multipliers, Chance x2 and three buy options. The slot has enough depth to keep the grid busy without making the whole thing feel like homework.

• Basics: Frenzy Clusters uses cluster pays instead of traditional paylines. A win is formed when 4 or more matching symbols land connected horizontally or vertically. When a winning cluster lands, the winning symbols are removed from the grid and new symbols fall into the empty spaces. This continues until no new winning clusters are formed.
• Hero selection: At the start of the game, players can choose one of 5 heroes: Golub, Olaf, Hugo, Bloke or Aussie. The selected hero appears beside the grid and reacts to the gameplay. The hero can be changed during the base game.
• Locked cells: Some positions on the grid are locked, meaning symbols cannot land there. A locked cell opens when a winning cluster forms next to it horizontally or vertically. In the base game, unlocked cells stay open only for the current spin. In Free Spins, unlocked cells stay open until the bonus ends.
• Special symbols: Special symbols can appear after a winning cluster disappears. They remove symbols from the grid but do not pay directly. The Rocket clears one full row or column. The Book removes symbols around itself. The Sphere removes all symbols of one random type.
• Scatters: Scatter symbols trigger the Free Spins feature. Landing 3, 4, 5, 6 or 7 Scatters awards 12, 15, 18, 20 or 25 Free Spins. More Scatters also give the feature a stronger starting multiplier.
• Free Spins: During Free Spins, a progressive multiplier applies to all winning clusters. The starting multiplier depends on how many Scatters triggered the round. Three random locked cells hide bonus multipliers, and when those cells are unlocked, their values are added to the main multiplier. Any Scatter that lands during the bonus also increases the multiplier by +1 from the next spin.
• Mega Free Spins: Mega Free Spins is the stronger bonus mode. It starts with all cells and bonus multipliers unlocked, giving the feature more immediate potential than standard Free Spins.
• Feature Buy: Frenzy Clusters includes one chance booster and three direct buy options.
  • Chance x2 adds 25% to the bet and doubles the chance of landing Scatters.
  • Free Spins costs 100x the bet and activates the standard Free Spins feature.
  • Mystery Bonus costs 137.5x the bet and randomly awards either Free Spins or Mega Free Spins.
  • Mega Free Spins costs 250x the bet and activates the stronger bonus mode with all cells and bonus multipliers unlocked.
