Funky Games brings us a new title called Thunder Blackjack which features exciting multipliers for bets. The player can power up their blackjack experience by achieving certain combinations and therefore unlocking multipliers values for the next bet. The game is played with multiple decks and a single hand.

Bets can go wild with anywhere from $5 to $5000. That said, there is a massive fee due to the multipliers which cannot be turned off. On the bright side, players can win up to 25x their bet for massive payouts. It all revolves around chaining together consecutive wins so it is slightly similar to a previous game we reviewed High Streak Blackjack.

The RTP of the game is 99.26% which is below the industry average. Let us check out the details of this Thunder Blackjack review.

Game Rules & Features

In Thunder Blackjack by Funky Games, you will find a standard blackjack ruleset with multipliers enabled. As for the basics, the game is played with multiple decks. There is no multi-hand option. The dealer will stand on all 17s and above. Each win you achieve is added to the history board you can access through the Settings button.

All the standard blackjack options are available including splitting, doubling, insurance betting etc. The game is played on a smooth blue velvety table with golden-black cards. As soon as you start up the round with a bet you will be able to see the multipliers at the top.

To activate a multiplier you will have to win the round with a certain combination. Then you get increasing multipliers for the next round based on your hand values. Higher values get you a higher multiplier for the next round. The cut-off values are 4-17, 18, 19, 20, 21, and Blackjack. A blackjack win can get you up to a 25x the bet multiplier for the next round. Multipliers start at a minimum of 2x.

If you lose the bet, you lose the multiplier as well. Furthermore, a 100% betting fee is in place to compensate for multipliers. This is quite a steep number and is generally the reason for the low RTP value of 99.26%.


Payouts in Thunder Blackjack can vary drastically due to the multiplier mechanic. To start off, the player can bet anywhere from $5 to $5000 to reach the standard payout. However, if they win the round, the next round will be boosted by a multiplier if they win again. These are the standard payout values:

  • Blackjack – 3:2
  • Regular win – 1:1
  • Insurance – 2:1
  • Multiplier – 2:1 up to 25:1

The overall RTP value for Thunder Blackjack by Funky Games is 99.26%. It is a lower RTP than usual according to blackjack standards and this is largely due to the 100% betting fee for multipliers.

Thunder Blackjack Strategies

Blackjack strategy is quite important in Thunder Blackjack. This is because the multiplier option is locked and is not optional. Essentially, you will always be betting with a fee as the multipliers are active all the time. This is why you want to make the most optimal moves all the time to score consecutive wins and benefit the most from the extra feature. Blackjack strategy charts are a great option to follow along with and minimize losses.

Overall, while the winning potential in Thunder Blackjack sounds amazing, in reality, the game suffers because of it. This is because the multipliers and consequently the 100% betting fee is always active. If you lose multiple games in a row you are not just losing your bet but double that amount. The low blackjack RTP value of 99.26% is proof of this. That is why we cannot recommend this release but it still might be a fun experience if you play it for free. If you like this sort of winstreak-based gameplay then High Streak Blackjack does a slightly better job at it.
