NetEnt and Big Time Gaming are among the providers named for GrandMasterJack. Together they created some of the most influential slots in online gaming. This guide explains Starburst, Gonzo’s Quest and Bonanza.

Starburst (NetEnt)

Space gems on five reels and one of the most played slots ever.

• Expanding wilds on the middle reels trigger respins.
• Wins pay both ways.
• Low volatility.

Ideal for relaxed sessions.

Gonzo’s Quest (NetEnt)

A Spanish explorer searches for El Dorado.

• Avalanche reels: winning symbols break and new ones fall.
• Multipliers rise with consecutive avalanches.
• Free falls with higher multipliers.

Medium volatility.

Bonanza (Big Time Gaming)

A gold mining theme and one of the first Megaways slots.

• The number of symbols on each reel changes every spin.
• Cascading wins.
• Free spins with an unlimited multiplier.

High volatility.

How Megaways works

Each reel shows a random number of symbols each spin. With six reels, the total ways to win can exceed one hundred thousand. More ways does not mean more wins every spin. It changes how wins are spread and usually increases volatility.

Smart habits

• Match stake to volatility.
• Set deposit limits and reality checks.
• Do not chase features.

Mixing styles in one session

Some players split a session between a steady game and a more volatile one, for example most of the budget on Starburst or Gonzo’s Quest and a smaller part on Bonanza. Decide the split before you start and keep to it.

Trying each game

Play a few minutes of each title at the lowest stake. Watch how often wins appear and how features trigger. This shows you the real pace of each game and helps you choose stakes that suit your budget.

Sequels and Megaways versions

Many NetEnt and Big Time Gaming titles have sequels and Megaways versions. They can look familiar but play very differently, often with higher volatility. Read the paytable before switching between versions.

Volatility and stake size

Starburst’s low volatility means wins arrive often but stay small, so a slightly larger stake can be comfortable. Bonanza’s high volatility means long quiet spells, so a smaller stake helps your session last. Gonzo’s Quest sits in between. Matching stake size to volatility is one of the simplest ways to keep sessions enjoyable.

Why these games still matter

Starburst and Gonzo’s Quest set standards for design and features that many later slots followed, and Bonanza helped make Megaways one of the most popular mechanics in online slots. Playing the originals is a good way to understand where many modern features come from.
