Tidal Riches by Greentube, Novomatic‘s online arm, is an iconic slot game. Launched way back in early 2019, it was a bit of a predecessor to the Megaways engine we’ve come to know and love. It has dynamic reels and can increase slot grid from a standard 5×3 layout to a 6×5 layout. So, you can have between 20 – 50 pay lines. Tidal Riches slot is set on a sunny tropical reef, with colourful fish and dolphins on the reels. As the name suggest, when the tide is high, so too are the wins. Let’s see what our friendly red octopus has in store for us.

How To Play Tidal Riches Free Demo Slot
How To Play Tidal Riches Quick Guide
Initially, when you start Tidal Riches you’re greeted with a 5×3 reel setup and 20 pay lines. Your primary goal is to match symbols from left to right across these lines. Moreover, winning combinations can unlock additional rows and reels, expanding your play area up to a 6×5 grid and increasing pay lines up to 50.
- Set Your Bet: Choose a bet from £0.20 – £10.00. You can also opt for the High Roller bets which cost 5x or 10x your betting stake.
- Spin the Reels: Press the Start button to spin the reels. If you prefer a more hands-free gameplay, select the Autoplay option.
- Expand The Grid: Consecutive wins light up arrows on the trail. This in turn can unlock more pay lines and also trigger the free spins bonus round.

Winning combinations light up arrows on the Arrow Trail at the top of the slot. Thus, leading to an expanded grid and more pay lines. Four or more consecutive wins will activate the Free Spins feature, introducing new symbols and opportunities for big wins. When there are no more wins, then the grid will reset.
Winning Combinations & Payouts
Landing three or more adjacent matching symbols on a pay line, triggers a payout. Your win is determined by the symbol involved in the winning combo. There are a total of 10 common symbols in Tidal Riches.

- High-Value Symbols: Dolphins, Octopi,Turtles, Pufferfish and Moorish Idols pay out the most. Landing 3 – 6 of the same symbol on a pay line can pay between 0.2x – 30x.
- Low-Value Symbols: Card symbols (10, J , Q, K and A) are the usual low paying symbols. They pay out between 0.1x – 1x.
Special Symbols
Tidal riches also features two special symbols: Wilds and Treasure Chests. There are no scatters in this fishing slot, as there is a bonus trail instead.

Wild Symbol
The Wild symbol in Tidal Riches substitutes for all common symbols. They can appear as single symbols or mega symbols as big as 3×2 in size.

Treasure Chest
During the Free Spins feature, Treasure Chest symbols are added to the reels. These symbols explode to reveal matching symbols. So, they are like mystery symbols.
Base Game Features
Tidal Riches includes several features within its base game:
- Cascading Reels: A feature that removes winning symbols from the reels, allowing new symbols to fall into their place. This can create consecutive wins on a single spin, lighting up the Arrow Trail.
- Hi Roller Option: There are two options both giving 3 spins, silver or gold. Silver costs 5x your bet and adds Mega Wilds to the reels. The Gold Spins costs 10x your bet and adds Mega Wilds and the Arrow Trail does not reset during the spins.
- Gamble: If available in your region, whenever you get a win you can choose to double it. The gamble options are the standard red card or black card. With a history trail so you can see what cards came before.
Arrow Trail
There are 2 arrow trails in the game. One for the base game and one in the bonus round. Every win lights up an arrow on the Arrow Trail. For visual effects, the tide will rise, unblocking a row of symbols. When there are no more wins, then the bonus trail resets. Progression along the trail in the base game looks like this
- One Arrow: Increases the grid to 6×3 with 20 pay lines.
- Two Arrows: Increases the grid to 6×4 with 40 pay lines and both way payouts.
- Three Arrows: Increases the grid to 6×5 with 50 pay lines and both way payouts.
- Four Arrows: Awards five Free Spins with treasure chest symbols.
- Five Arrows: Adds stacked treasure chest symbols to the Free Spins.
- Six Arrows: Adds mega chest symbols (2×2) into the Free Spins.
- Seven Arrows: Adds colossal treasure chest symbols (3×2) to the Free Spins.
Tidal Riches Free Spins Bonus Game
You trigger the free spins bonus round via the base game arrow trail. This is done through 4 – 7 consecutive wins in one betting round. Once triggered, you’re awarded five free spins. During these free spins, the game can add treasure chest symbols into the mix. When they land, they act as mystery symbols and can turn into one of the common symbols

In the bonus round, there is a new bonus trail. Each consecutive win during the free spins lights up an arrow, with the potential to award additional spins. If you have 4 -7 consecutive wins, then you can trigger 4 -10 additional spins in the bonus round. There is no limit to re-triggering more spins.
Furthermore, if you manage to progress far enough on the bonus trail, then you will also unlock better treasure chests. They can appear as single cells, stacked chests, mega symbols (2×2) or colossal symbols (3×2). Once all bonus spins are completed, then the bonus round ends.
Tidal Riches FAQ
The Return to Player (RTP) for the game is 95.26%.
Even though Tidal Riches is an old game, it has been developed with HTML 5.0 technology. Therefore, all mobile online casinos that offer Novomatic games, will be the right place for you to play this game on a mobile device.
Free Games are triggered by lighting up at least four arrows on the Arrow Trail. You can do so by landing consecutive wins.
The maximum win is 12,500x your bet. But to reach this pay out you will need to trigger additional spins, colossal and stacked chest symbols in the bonus round.
Conclusion
Tidal Riches by Novomatic is a slot with dynamic gameplay. Moreover, Arrow Trails make the game more interesting, unlocking more pay liens or bonus features along the way. RTP of 95.26% is slightly below averages but is compensated by a potential max win of 12,500x. The game’s medium volatility will keep you playing longer but it still has the ability to pay out quite well when the symbols align. For an old timer, the game is still a lot better than some of the newer fishing slots out there.
