#2 Jackpot 6000 (NetEnt) – Up to 98.8% RTP

Jackpot 6000 is a thrilling classic slot machine from NetEnt with a real old-school vibe. You can play with up to 5 paylines active, betting between 1 and 10 coins per spin. It is highly recommended to play with the maximum bet of 10 coins however, as this creates the possibility of triggering Supermeter mode. In this game mode, you can win a mystery prize of between 10 – 6000 coins when just 2 joker symbols land anywhere on the reels. Also, getting 3 jokers on a payline in Supermeter mode guarantees a jackpot payout of 6000 coins. When you play Jackpot 6000 with 1 – 8 coins, the RTP is a paltry 74.9% – 79.2%. Yet with 10 coins in play, the RTP ranges from 95.1% – 98.8%. The variance is because Supermeter mode is skill based, so you can directly impact the outcome.

#1 Mega Joker (NetEnt) – Up to 99% RTP

Whilst Jackpot 6000 boasts an extremely high RTP, it is just beaten to the top spot by another NetEnt classic slot; Mega Joker. Bet with just 1 coin and the RTP is an underwhelming 76.9%. Yet on the other hand, a max bet of 10 coins elevates the RTP to between 89.1% – 99%. Furthermore, it provides bigger payouts and the Supermeter mode. In Supermeter mode, you need to choose the bet level and the optimum level at which to collect your winnings. It is this element of skill which can increase the RTP. The skill component, retro style and engaging gameplay make Mega Joker a firm favourite with players.

300 Shields by Nextgen is based on the epic battle between 300 well-trained Spartan soldiers and a huge Persian army. This slot offers thrill-seeking slot players an unusual premise: a multiplier of 300x. This is the highest multiplier we have ever seen on a slot machine. It is reached by collecting shields in the bonus round – find enough of them, and you will win free spins with that enormous 300x multiplier (on wins with a wild symbol).

Gonzo’s Quest has become such a popular slot that scores of clones have been developed – but none have the charm and magic that Gonzo’s Quest has.

High variance versus a high return to player

High variance is not the same as a high return to player (RTP). The return to player is a percentage that depicts how much the slot machine will pay back to the player, calculated on average over an extended period. The variance of a slot is more focused on the short-term and is a good indicator of the “risk”, that is involved with that slot machine. To put it simply, a low variance slot machine is a “low risk” slot machine, which offers lots of small wins and a medium win, now and then.

A high variance slot is a “high risk” machine. It will not pay out a lot of winning combinations but will award a massive win from time to time.

Whether you prefer low variance or high variance slots, it is also recommended always to play slots with a high RTP. If the RTP of a slot is 97%, this means that out of every £100 that is put into the machine, £97 will be paid back to the player on average over an extended period.

Why do players like to play high variance slots?

Some casino players have a strong preference for high variance slots. These players know and accept the increased risk that high variance slots bring, in exchange for a genuine chance of hitting a monster payout. They know that they might not win most of the time, but they will hit a mega jackpot sometimes.
