White Rabbit – An Alice-Inspired Adventure
| Slot Name | White Rabbit |
|---|---|
| Software | Big Time Gaming |
| RTP | 97.72% |
| Best Casino | Casino Gods |
Inspired by the fantasy adventures of Alice in Wonderland, White Rabbit boasts a Megaways mechanic in the base game and a 97.24% RTP that rises to 97.72% with the bonus buy mechanic. Fans of the classic tale will be impressed both by the design of this slot, and the fun gameplay mechanic that come with it.
White Rabbit is a joy to play thanks to its stunning visuals and bold colours. A trip down the rabbit hole awaits all those who choose to spin the reels of this fun-looking slot. But it’s not all about the aesthetic, here.
The free spins feature can be triggered, or purchased via the Feature Drop with a cost that goes down if certain symbols land. While you can buy the free spins game at any point, every time one of the Drop symbols arrives anywhere on the reels, the cost of buying the feature will decrease.
During the free spins feature, reels start at between five and seven rows in height, and can grow during the feature up to a maximum of 12 rows. A nice little nod to the source material, and an exciting mechanic for the player.
The cost of the bonus buy starts at 100x your bet, which is still lower than some others, even before the Feature Drop.
Extra Chilli Megaways – Thousands of Ways to Win
| Slot Name | Extra Chilli |
|---|---|
| Software | Big Time Gaming |
| RTP | 96.15% |
| Best Casino | Ladbrokes |
Another Big Time Gaming slot with the Feature Drop mechanic, Extra Chilli is a colourful, Mexican-inspired slot with up to 117,649 ways to win on every spin thanks to the Megaways engine. There is also a cascading reels mechanic, seeing winning combinations disappear to have others fall in their place for the chance of consecutive wins.
Bright colours adorn all corners of the reels, with a Mexican town in the background and a suitable soundtrack providing the background. The attention to detail is impressive, and really helps bring the design of the slot to life.
You want to land the H, O, and T symbols to trigger the free spins feature, but collecting Feature Drop symbols makes the bonus buy option less expensive, too.
Four free spins are given when you trigger the feature, and a multiplier rises by 1x with every cascade win gained during the bonus round. That multiplier does not stop when a cascade does, instead it locks in place for the whole feature, growing further with any additional cascades.
The currently displayed multiplier will be added to all wins on the current spin or cascade. Additionally, landing bowls of chilli icons beneath the reels will trigger more spins, still not resetting the multiplier.
Rick and Morty Megaways – A Brilliant Cartoon Adaptation
| Slot Name | Rick and Morty Megaways |
|---|---|
| Software | Blueprint Gaming |
| RTP | 97.05% |
| Best Casino | Videoslots |
Blueprint Gaming’s Rick and Morty slot game is based on the cult classic cartoon of the same name.

Not only visually impressive, this feature-rich slot has a max win of 50,000x your bet.
Rick and Morty is packed with bonuses including a very exciting free spins feature. There’s a choice of three different free spins feature when you trigger the bonus game, which you can choose from, or pick a random combination of spins (up to 50) and modifiers.
The slot has a 96.55% RTP in the base game, and this rises to 97.05% in the bonus game. If you don’t want to wait for the required number of scatter symbols to land, for a cost of 150x your bet you can take yourself straight to the free spins feature.
When buying the bonus, the mystery free spins feature is the only option, so you won’t be able to choose the number of spins or the modifier, upping the risk level a little. It’s worth weighing up the risk vs reward here before choosing whether to take this option.
If you want to buy the bonus, it will cost you 150x your stake, which is higher than some others, perhaps due to the high volatility of the bonus game.
Dead or Alive 2 – A Modern-Day Western Hit

|---|---|
| Software | NetEnt |
| RTP | 96.82% |
| Best Casino | Ladbrokes |

The design of the slot is fantastic, with various outlaws appearing on the reels, each created in a playful and entertaining cartoon style that adds to the fun vibe of the slot.
If you enjoyed the first Dead or Alive slot, this one is guaranteed to float your boat. It’s kept the feel of the original, but both the graphics and gameplay have been enhanced considerably. While the original slot has reached classic status, Dead or Alive 2 feels modern and exciting.
Landing three scatter symbols will trigger the game’s free spins feature, here you have a choice of three potential versions of the bonus, each offering its own modifier such as increasing multipliers, locking wilds, and even a suyper high volatility bonus game with a max win of 100,000x your bet.

Continuing the theme of Western inspired slot sequels, Money Train 2 sees the RTP jump from 96.4% to over 98%, when you opt to use the bonus buy mechanic.
In the base game, the respins feature keeps things interesting, guaranteeing a win when it triggers, and building a multiplier for every non-winning spin on the way to the eventual payout.
However, it’s the main feature, the Money Cart Bonus, that is the one to look out for when playing Money Train 2. This feature sees all symbols disappear from the reels, and the player is then given three respins.
Every time any symbol lands, the spin count returns to three, the round continues until all positions on the reels are filled, or the spin counter reaches zero.
All symbols landing on the reels are useful, they may offer cash prizes, or enhance the total already collected. When the Money Cart Bonus round finishes, all collected values will be combined for a total payout.
This feature is triggered from the base game, but if you’re in a rush to try it out, you can get yourself straight there by buying the bonus for 100x the bet value.

This excellent Pragmatic Play title has a bonus buy mechanic, too. For 100x your stake, you’ll trigger a feature with a max potential jackpot of 21.000x your bet value.
It’s a simple free spins bonus here, 10 spins and a payout for the triggering scatters. You can also gain an additional five spins if you land three or more scatters during the feature, so the spin count can rise here if the reels fall in your favour.
