What is the WinWinBet promo code Sri Lanka?

The promo code meant to allow you to activate the 100% bonus is CSMAX, and here’s a breakdown of the bonus claimable.

How to use the WinWin LK promo code bonus

Before we go into detail, it’s important to note that the promo code CSMAX can only be used during registration, and if you skip the process, there’s no way to use it after registration. See details on how you can use the promo code below.

1️⃣ Visit WinWinBet’s website

You can click here to go straight to the website, or just click on any of the “JOIN WINWINBET TODAY” buttons, and you’ll be taken to the website where you can start your registration.

2️⃣ Start the registration process
Just at the top-right corner is a registration button; click on it to be directed to the sign-up page. For sign up, WinWinBet will present you with 4 options, and that includes registering with your phone number, one-click, email, or social media. Though email is what’s recommended, the one-click method is still the fastest.

3️⃣ Enter the promo code
On any of the options, you’ll see a section to add a promo code. That’s where you enter the promo code CSMAX and also select the bonus for sports, as shown below. Remember that you’ll need to select a sports bonus to qualify for the bonus.

4️⃣  Activate sports welcome offer
If you continue without being sure that you have the sports bonus selected, you can always confirm. To confirm, click on your profile, click on the promo menu, and then click on bonus for sports.

5️⃣Make a deposit

There are over 30 payment options available on WinWinBet, and that includes e-wallet options, bank transfer, Internet banking, and cryptocurrency. Avoid making deposits with crypto because they don’t qualify for bonuses on the platform. I recommend you use iPay, copy the shown UID, enter the deposit amount, and head to your iPay app.

6️⃣Transfer from your iPay App

On your iPay app, go to the payment page and enter the copied ID and the amount you want to transfer. Once completed, click on pay and copy the transaction ID. Don’t forget that you need to deposit a minimum of 333 LKR if you want to claim the welcome bonus.

7️⃣ Complete the transaction on 1xBet

Once you’re done, open your WinWinBet iPay deposit page, input the amount you sent, enter the copied transaction ID, and click on the confirm button. Once you follow the steps listed, your deposit will be processed and credited to your account. JOIN WINWINBET TODAY

• You need to insert the promo code CSMAX during registration. After registration, there’s no adding of promo code

How to make the best use of WinWinBet LK welcome bonus

Rather than just carelessly betting the sports bonus, there are a few tips you could follow to get the best out of the welcome bonus you get.

Place qualifying accumulator bets

The rule says that only accumulator bets qualify, so ensure your selections meet the requirement, and to be on the safe side, only place accumulator bets with 3 selections. But, if you must have more selections, make sure you’ve researched them and they have a higher chance of coming out successful.

Bet on sports you understand

Just because this is a bonus, it shouldn’t be the reason it’s misused. If you’ve always been betting on Football, then stick to football betting. There’s really no need to start exploring new sports if you want to maximize the promo code bonus.

Keep track of days and wagering

Since the timeframe is short, you want to make sure you’re tracking the days so you finish the wagering before it expires. Also, you can keep track of the wagering as you bet, so you know when you’ve fulfilled the requirement and can make withdrawals.

WinWinBet casino welcome bonus

One of the reasons why the promo code CSMAX is one of the best promo codes in Sri Lanka is that it works for both sports and casino welcome bonuses. If you’re more interested in a casino bonus, WinWinBet has a welcome bonus for casino players.

The casino welcome bonus is a welcome package that’s up to 140,000 LKR plus 150 Free Spins. This casino bonus is spread across your first 4 deposits, and we break them down below:

Rules of WinWinBet Casino Promo Code 

• The minimum deposit that’s required to receive the 1st deposit is at least 200 LKR, while the 2nd to 4th bonuses require a minimum deposit of 400 LKR.
• You will only be given the free spins after you have completely wagered your bonus.
• The bonuses come with a wagering requirement of 35x, and it’s only valid for 7 days each.
• The eligible bets that you place in the WinGames section are counted twice toward the wagering.
• You cannot get another offer until you have fulfilled the requirements for this bonus.

Since playing WinGames counts double towards the wagering, it’s best to focus on betting on those games so you can easily fulfill the requirement for the bonus. For the free spins, you should remember that they’re specific to certain games; for example, the free spins you get from your second deposit can only be used on Juicy Fruits Sunshine Rich.

Existing player bonuses at WinWinBet Sri Lanka

After you claim and use the welcome bonus, there are several other ways that you can continue getting bonuses on WinWin Bet. Here are just a few of the bonuses available on the site.

Lucky Reload

When you make your first Monday deposit of at least 200 LKR, you can receive a 200% bonus that’s worth up to 4,000 LKR, plus up to 1 free spin that’s to be used on Mariachi Afortunado. The bonus has a 35x wagering requirement that must be completed within 48 hours of receiving the bonus. The maximum you can bet per spin is 200 LKR per spin.

Success Guaranteed

This is a bonus for sports bettors, and it’s to reward you for your losing streak. If you have 20 losing bets in a row, you’ll be given points that you can later exchange for promo codes. The number of points you get depends on the average size of your losing bets.

Advancebet

This bonus allows you to place bets even when most of your balance is tied up in unsettled bets. In simple terms, even if your bet has not settled, you can still use the potential win to place live bets or on matches that are starting within 48 hours. 

If the first bets win, the Advancebet amount is deducted from your winnings. However, if the first bets lose and your balance cannot cover the borrowed amount, the Advancebet wagers are canceled.

WEEKLY Rebate

This is the bonus that allows you to get cashback based on the eligible bets that you place during the previous week. Every Tuesday, you get 0.3% of your qualifying stakes as a rebate, but the minimum that WinWin pays out is 405 LKR, and the maximum is 404,227 LKR. 

The bets that qualify for this offer are bets with odds of at least 1.50; meanwhile, esports, virtual sports, totals, handicaps, and refunded bets are excluded.

Win and Invite

This is a referral program that allows you to invite friends and earn money. When friends register with your link, make deposits, and start betting, you get to earn a percentage of the net profit generated by those players.

These are just a few of the bonuses that are claimable on WinWin Bet. When you check the promotion page, you’ll find many other bonuses that are claimable after you fulfill the wagering requirements for the welcome bonus.

This is one of the features I like most on the website, and that’s because as you place bets on the platform, WinWin Bet will keep giving you points, and those points can be converted to promo codes that can be used for betting. The minimum points you can convert are 50 points, and it is only the bets that you place with real money that get rewarded with points. 

As you place bets, ensure you’re checking the promo code section so you can convert eligible points to promo codes.
