1. Dragons Clusterbuster

The best 9 reel slot for real money is Dragons Clusterbuster. 

Dragons Clusterbuster is a fantasy-themed online slot with fiery dragons and flame-fueled features. This 9x9 high-volatility game comes with amazing visuals and action-packed gameplay. The slot has cascading reels and a cluster pays, meaning if 5 or more matching symbols appear on the grid, they award a win. 

The excitement of the game lies in its features and bonuses. In the middle of the grid, there is a massive, 3x3-sized dragon's egg, which is the Clusterbuster. If you manage to crack the tiles around it, the egg unlocks multipliers and wilds, replaces low-value symbols with premium ones and takes you to the bonus round with free spins. 

2. Elemento

Elemento is a 9x9 grid slot with unique and highly volatile gameplay. Everything starts with the 4 elements that are the wild modifiers: fire, water, earth and air. Fire shoots more wild symbols to the grid, water transforms 9 symbols into matching ones, earth removes low-value symbols and air transforms or removes symbols.

In addition, there are multipliers, scatter symbols and bonus rounds with free spins. The gameplay is entertaining from the beginning. The outstanding features, bonus games, the maximum win of 16,000x and the quirky characters on the grid guarantee no dull moments. 

3. Cash of Command

Cash of Command from Play'n Go is a thrilling cluster pay slot. The high-volatility game takes you on a battle-filled adventure with three Naval Heroes and their treasures. The slot blends outstanding visual effects and board game-style gameplay perfectly.

The idea is to collect winning symbols to unlock the modifiers that attack the grid, such as submarines and warships. They are sent by the Naval Heroes and grant you more wilds and mega symbols. They also turn random symbols into matching ones.

And this is not all. The turrets on the side shoot wilds to replace random symbols after any non-winning combination. This can turn the gameplay upside down and kick off a winning streak. 

4. Good Luck Clusterbuster

Good Luck Clusterbuster is a cluster pays slot from Red Tiger. The vivid slot with an Irish luck theme is played on a large 9x9 grid, and you will need at least 5 matching symbols to form a win.

There is a huge Pot of Gold in the middle of the grid. If you manage to break the inactive tiles around it by forming a winning cluster that hits adjacent to it, you'll jump to the bonus round with free spins.
