Siam99 online casino review

If you are purposefully looking for an online casino with a flexible bonus system and a generous loyalty program – most likely, you have already heard about Siam99. The administration of this project makes every effort to attract the attention of new customers and increase the loyalty of the existing base.


The website of this casino is compatible with the major payment systems used in Thailand.


Bonus offers at Siam99

An extensive bonus program is one of the main competitive advantages of the project. Before registering in the system, it is recommended to search the internet for promo codes for a welcome bonus.

If you enter such a code when you create your account, the amount of your first deposit will be doubled. The maximum increase limit is $7,500 – and that’s a lot compared to what other sites offer. Also, each newbie gets 40 freespins for 5 days for a popular Siam99 slot with a maximum win of $2,500 – again, this is very generous.

Third-party resources on the Internet periodically publish promo codes, which can be used not only by newcomers, but any players who have an account in this casino. These promo codes can accrue a variety of prizes, but most often they are freespins.

On Mondays, players are credited with a 10% cashback. They are available only to those users who made bets for the previous week for an amount that exceeded their winnings by at least $100.


Simply put, the cashback is calculated based on the amount of money lost. For cashback, only bets made on Siam99 slot machines are counted, without the participation of games with live croupiers. Wagering this bonus is also allowed only in slots, not in live casino.

Wager in this case is x5 and does not change depending on the status of the player in the loyalty system. Such a low wager is a rarity for modern casinos, where even the figure of x20 is perceived as an attraction of unprecedented generosity. You are allowed to win back cashback within 72 hours after it has been credited.

On Thursdays there is a deposit bonus: if you deposit the account for $30 or equal to that amount in another currency, the gambler will receive a gift of 25 freespins for a popular slot machine.

Also, the platform regularly holds tournaments, information about which is published on the right side of the site. Tournaments are a competition for a particular game.

Choice of slots and gambling games in Siam99

A menu with links to different categories of games is located at the top of the site. The catalog of entertainment includes slots, roulette, table games, live casino format games with live dealers.

The range of entertainment is extensive enough to make a beginner’s eyes run wild, and experienced players stay on the platform for many hours. The platform features slots with different volatility: high, low, medium – as well as a variety of themes, plots and design.

Along with icons of slots, the main page displays statistics of the most successful gamblers who are currently playing and winning on the site. This information is made on the right side of the page.


The name of the winning player, the name and icon of the slot, which brought him luck, as well as the amount of winnings. The information is updated in real time – and the site visitor becomes a little envious of the fact that other people are right now getting money and enjoyment. This is very good motivation to create an account in the system and join the game process immediately.
