How to Play

You can play 1 Reel Reef like this:

  1. Open the slot on smartphone or PC
  2. Wait for it to finish loading
  3. Place a bet between €0.01 and €10
  4. Click on "Start" to spin the reel

There are no traditional lines in the game, but there are 3 pay symbols. Each of them has a separate meter. It gradually fills up when the corresponding symbol appears on the reel as a result of the spin. With each filling stage, a certain bet multiplier is activated. At the same time, all winnings go into the bank. If you take money from it, the progress of the counters reset.

On the control panel of the slot, you can select the size of the bet, as well as turn off or turn on the soundtrack. There is also the Collect button, with which the winnings are transferred from the bank to your balance. In the lower right corner, there is the "?" button that opens the paytable.

1 Reel Reef RTP and Volatility

6.4 
The RTP of the slot is 91.55% and the volatility is high.

Return To Player is the theoretical percentage of bets that should be returned to the player after a very long gaming session. The value of this indicator is often overestimated, but 91.55% is still too low. Typically, in modern games, the RTP is about 96%, less often - 94%. The reduced RTP may indicate the provider's uncertainty that the game balance is set correctly.

At the same time, the rules of the game do not exactly specify the volatility indicator. According to our observations, it is high. Typically, this volatility value means that the prizes in the game will not appear too often.

Theme

8 

The graphic design of the game conveys the atmosphere of the underwater world quite well. The playing field is located at the bottom of the reservoir, which is slightly enlivened by bubbles rising. The rest of the elements of the slot look rather poor. In general, the design of the slot does not make a very optimistic impression.

The soundtrack of the game is also far from perfect. During the rotation of the reels, a cheerful Hawaiian melody sounds, but it is too intrusive and monotonous. In our opinion, the soundtrack should be turned off as soon as possible.

There are 3 payment symbols in the slot – the Starfish, Clownfish and Seahorse. There is also the Wild. It is counted as all three symbols at the same time and replenishes all three meters. The last element of the game is the Crab. It resets progress on all counters. According to our observations, the Crab appears in the game most often.

About Spinomenal

Spinomenal is a major provider that has been developing games since 2014. The main goal of the company is to create a variety of content on the most unexpected topics. At the same time, the provider is engaged in the mass development of slots with standard game mechanics.

Bonus Rounds & Free Spins

6.9 

There are no usual bonus rounds like free games. Since the slot has only 1 reel, the developers had to come up with something new.

Progressive Symbol Wins

If any of the 3 pay symbols appear on the grid, the corresponding meter is replenished. With each step of the meter, the win multiplier also increases. For example, on the first level of the Starfish, you will receive a payout with a 1x bet multiplier. On the second one, it will grow to 2x and so on, up to 12x bet.

The best multipliers are given by the Seahorse. At the first level of the meter, the player can take the winnings with a 10x bet multiplier. This indicator rises to 250x at the top level of the meter for this symbol. But that's not all. If you manage to fill three meters, you get a jackpot of 500x bet.

However, do not forget about resetting progress. The ubiquitous Crab can appear at any moment and cancel all your achievements. The rules of the game say that a good result can be shown if you take the winnings after reaching the first step of the Seahorse meter. This will deprive you of a possible jackpot, but will significantly reduce costs.

Max Win

6.5 

Maximum win — 500x bet.

It is quite simple to replenish meters in the game. The desired symbols appear on the grid relatively often, and the win multipliers are really good. However, the Crab does not sleep. Don't forget about it and it won't bring you much disappointment.

Overall Rating

7

Winning: €5
Multiplier: x26
A tricky one-liner, where you must find the balance between risk & rewards.
The slot is about building a cumulative and then cashing out in the right moment. Not that easy of task, especially if u lack patience and self-awareness. IMO, the best strategy here should cashing out 8 of 10 x10 wins, and risk on 2 other series. Pareto principle in action!
It’s easy to losing ur mind here, especially with that funny atmosphere. Be cautious and rational here.

1 Reel Reef is a slot that has 1 reel... Captain obvious on duty. Yet another one reel slot, that lacks design, atmosphere and feature. Aside of that you will certainly feel pressure of making a decision whether you should or shouldn't collect the win you have already accumulated. Be ready to witness some dead spins, with no wins and be ready to lose even 1x bet size you have already collected. Slots like these are just horrible and pointless. The rtp is crazy low and it is made to drain money
