Bigger Bonanza Rush Express Demo and Slot Review 2025

Play For Free

If you want to play Bigger Bonanza Rush Express, you can try it here in the demo mode.

I think Bigger Bonanza Rush Express is a really fun slot with lots of interesting features. The mining train theme looks great and is very eye-catching with pretty jewels and an ethereal background. Also, the paytable could be clearer, as it fails to mention what some of the game’s mechanics actually are, but once you get to those mechanics, they are grand. This is especially true with the generous ‘Rush Express Feature’, which collects the net value of gems you’ve collected and returns it for very generous prizes. 

The game has fixed betting amounts, instead of you being able to manually adjust your bet, which I think is a little bit of a shame, as this limits your choices when betting.

Bigger Bonanza Rush Express’s free spins add a very enjoyable element to the game, triggered by the gems you collect, which makes you feel like you’re down in the mines, really collecting these jewels. This gets better when the free spins give you an additional mechanic based on the colour of the gem collected.

The only feature I didn’t get to enjoy was the golden nugget ‘Pick Feature’, which seemed harder to trigger than the other features, but this didn’t stop the slot from going full speed ahead.

Some Technical Considerations About Bigger Bonanza Rush Express

Diving into Bigger Bonanza Rush Express’s more technical mechanics, the slot has a hypothetical Return to Player (RTP) percentage of 96.51%. This is the theoretical payout percentage of the game, which means the higher the RTP, the more you would theoretically be paid out. 

The average for most slot games sits at around 96%, which puts Bigger Bonanza Rush Express slightly above average. Bigger Bonanza Rush Express is a slot with high volatility, meaning that it will pay out less frequently compared to other games, but will potentially be more generous when it does.
