Microgaming launched the safari-themed Mega Moolah progressive jackpot slot in 2006 to much acclaim. In 2015, it paid out a £13.2 million jackpot to British soldier Jonathan Heywood, from a minimum 25p stake. NetEnt was the first to break the 100k barrier with Dead or Alive 2, offering a maximum payout of 111,111x your stake. They later surpassed this with the release of Starburst XXXtreme, which offers a 200,000 max payout. Their selection also features Dream Drop progressive slots, with the gritty Wild West-themed Money Train Origins standing out as a highlight. A measure of how frequently and how much a game pays out, indicating the level of risk and potential size of wins over time. Starburst by NetEnt is a dazzling space-themed slot known for its vibrant expanding wilds and both-ways win mechanic. The sleek visuals and hypnotic soundtrack bring cosmic replayability.

Multipliers matter most in combination with another feature. A 2x wild multiplier during free spins will usually pay a lot more than a multiplier landing during the main game. Bonus games and pick-and-click rounds are worth a few demo runs specifically to see the range of outcomes. A wide range between the smallest and largest prize on offer usually means the bonus feature is rather volatile. Many people don’t realize that free slots and real money slots use the same math principles. RNG (random number generator), RTP (Return to Player) and hit frequency don’t change based on whether the slot is played for real or free money. What changes is the feeling when you win for real money versus playing for free virtual credits.

As it’s one of the high volatility slots, you may find that it can take a while to get some decent wins.

Similar to fruities, such slot games present a familiar format but with various win line configurations.
