Online casino


Slots are such a popular game that never runs out of patrons due to their higher winning rate which is expressed in % return to player (RTP). An RTP that is greater than 90% is considered already good. In playing in an online betting site as a newbie, you must take this % return as your primary criterion.

All About RTP

Return to player is a betting term used to describe the payout that a player will receive throughout the betting based on its initial wagered money. This RTP can be solved using the formula below,

wherein the win refers to the amount accumulated by the gamer, and the turnover as the gross amount wagered.

Probability of Slots

Probability refers to the possibility of “something” to occur in which its value falls between 0 (no occurrence of events) and 100 (the event always occurs). This can be calculated using the formula below.

Before playing, a bettor must know the difference between probability and odds since these are the common terms used in betting games. If probability depicts the winning or losing chance of a bet in a game. The odds, on the other hand, refers to the ratio of the player’s losing chance to the winning chances. For example, if the odds are 1:1 (50%), the payout is called an “even money”.

Randomness in Slots

Randomness is a mathematical concept that represents the occurrence of an event in the real world. In the game, randomness also exists, and it is run by an algorithm called Random Number Generator. This randomness is not purely random at all because it is a mimicry or pseudo-randomness. This kind of system is employed in virtual slots to ensure equal gaming among the players.

Paylines and Pay Tables

Paylines refer to the sequential alignments of symbols that depict the winning combinations in the slots. These alignments can take many forms such as horizontal straight lines, diagonals, or even zigzag fitted in a display screen with a standard dimension of 3 rows by 5 reels. This dimension could also be increased up to its maximum of 4 rows by 6 reels which are common in progressive jackpots.

The figurative counterpart of the paylines is called the paytable that directly shows the corresponding prizes for each generated winning combination. Since slot machines employ an all-ways-win system, the number of probable ways to win combinations is x raised to the power of m (xm) where x is the number of rows and m is the number of reels. So, if the slot has 4 rows with 6 reels, its possible winning combinations is 46 = 4 x 4 x 4 x 4 x 4 = 4096. For the standard slots with 3 rows by 5 reels, the winning combination is 35 = 3 x 3 x 3 x 3 x 3 = 243 combinations. Therefore, the more reels are employed, the greater the chances of winning.

For Thai players, this kind of slots with high RTPs can also be found in Jili เครดิตฟรี (free credit).
