How to play

Diamond Mine is a straightforward three reel, one payline classic slot machine which is a little different from modern multi-lines machines. Though this slot machine game works like any other, the fact that there are just three reels and one payline adds to the challenge. Diamond, bar, seven and dollar are the symbols in this game.


The purpose of this three reel online slots is to simply line up the matching symbols on the single payline in the game. The payline is indicated by the straight red line right at the center of the reels.

How to Place a Bet

The gameplay in the Diamond Mine online slot is initiated after you fix the wager amount per game. You can increase or decrease the size of your bet by pressing the up and down arrows on the left and right side in the insert coin window. You can set your bet in the denominations of $0.05, $0.25, $0.50, $1.00 and $5.00. After that you can click on the $5, $25 or $100 chips to put in the credits into the slot machine. Then press the “bet one” tab to select the number of coins that you wish to play your game with. If you wish to bet just one credit on the game, click on the bet one tab once. However, if you wish to bet two credits, click on the bet one button twice. You can play with a maximum bet of three credits per game in the Diamond Mine online slots. Press the “Play 3 credits” tab if you want to bet with three credits in your game.

For instance, if you bet with one coin and get three Diamonds on the payline, you’ll win 50 coins. But if you bet with two coins and reel in three Diamonds on the payline, you’ll win 100 coins. If you bet with three coins and spin in three matching diamonds on the payline, you’ll win 150 coins.

There are a total of eight winning combinations in the Diamond Mine online Slots that offer you a chance to reel in some wonderful rewards. But do you know how often these winning combinations can show up on the reels of Diamond Mine online Slot to help you win these lovely prizes?

Some slot players have made an attempt to find this through the standard deviation theory. As the words “standard’ and “deviation” show, it is believed that there is an average number of times that the reels in a slot machine “deviate” to throw up nill results. Based on this, one can calculate the average of the number of empty spins before a winning spin occurs. Of course this is true of all slots, and you can try this strategy on any of them, not just the Diamond Mine strategy.

Follow the step-by-step procedure below to apply the standard deviation strategy:

  1. First ensure that the slot you are playing on is giving out “equal pay,” on your bets. “Equal Pay” is nothing but a proportionate value of your bet. For example, you wager $1 with one, two and three coins. The Diamond Mine slot pays you 2, 4 and 6 coins. You can see that a uniform percentage is maintained across the three levels.
  2. You can proceed to play the game now. Using a pen and a paper, keep a record of the number of empty spins that occur between every win. Do this for at least 10 winning spins. If you are playing for real, make sure you wager with the minimum bet size while you are calculating empty spins between your wins.
  3. When you have carefully traced the number of empty spins between your 10 winning spins, workout the average the number of empty spins between your winning spins.

The example below shows the series of 10 wins that can help you understand the pattern in which you can trace the empty spins between your wins:

  1. Let’s assume that you get your first win after 8 empty spins and the second win after 10 spins.
  2. Then you reel in your third win after 9 empty spins and fourth after 11 spins.
  3. Subsequently, you get your fifth win after 14 empty spins and sixth win again after 11 spins.
  4. Your seventh winning spin comes after 13 empty spins and the eighth spin after 9 spins.
  5. Finally, you get your ninth win after 14 empty spins and the tenth spin again comes after 11 spins.

The example above clearly indicates that most of your wining spins occurred between 8 and 14 empty spins of which the maximum wins come after 11 spins. So, in a nutshell the average of empty spins between your wins is 11 spins. This means that there is a high probability of getting a win after 11 spins.

As this standard deviation strategy is a probability theory, CoolCat Casino doesn’t claim that this trick will always prove right. With the Random Number Generator installed in most online slots, your calculations of the average may well go awry. So while there is guarantee that you will win, there is no harm in trying.


Every gambler and every casino game has a set of dos and don’ts. When it comes to slots which is largely based on chance, there is no prescribed strategy. However some tips can help you play with prudence.

The Simple 3 Coin Strategy

Here, you need to bet with maximum credits in order to get higher rewards. In Diamond Mine online slots the highest paying combination is three images of the dollar sign. Let’s say, if you bet with only one coin and spin three images of the dollar on the payline, you’ll win a decent reward of 800 coins. On the other hand, if you bet with three credits and reel in the same combination of three dollar signs, you’ll win the highest jackpot reward of 2500 coins. The combination is the same…but betting the maximum coins can fetch the highest return in the game. We cannot deny the fact that luck is the prime element in winning slots. However, many slot machine fans follow such simple tactics to have a good time on Diamond Mine online slot.

High/Low Tip

The high/low works on the two extremes in the game. On this online slots you can bet a maximum of three coins and a minimum of one coin. The middle bet in the game is the bet with two coins. But it is not advisable to stop at Bet Two. If you are getting higher returns on three coins, you should bet with it. If however, you start losing with the three coin bet, jump to the one coin bet and start all over again.
