I review casino sites every week, and two names keep popping up in my inbox: Intermiami888 and X33 Online Casino Malaysia. Friends ask which one gives better value, which one pays out faster, and which one is more trustworthy. I decided to put both through their paces like a normal player in Malaysia — small deposits first, then a few longer sessions — and note what genuinely stands out.
What each brand is trying to be
Intermiami888 positions itself as a reliable, Malaysia-friendly site with tiered bonuses and a very clear focus on slots. The platform is verified through the BolaKing partnership, and the lobby plugs into familiar payment options such as FPX, Touch ‘n Go, GrabPay, Visa and MasterCard. Security logos aren’t just decoration here; you’ll find names like BMM Testlabs, iovation and ThreatMetrix alongside the usual SSL padlock.
X33 aims for breadth. You get slots, live casino, sports, eSports and even 4D lottery under one login, supported by big studios like Pragmatic Play, Playtech, Evolution, Allbet and SBOBET. For banking, the cashier supports Touch ‘n Go, GrabPay, ShopeePay, Boost, Visa, MasterCard and selected crypto, wrapped with 128-bit SSL and AI-assisted fraud checks.
Real promotions you can actually claim
This is where most reviews get vague. I prefer to list the real deals I saw on the promo pages at the time of testing.
Intermiami888 bonuses
- Welcome bonus 70% with a minimum RM100 first deposit, x5 turnover, and a RM388 cap; slots only and certain providers excluded.
- A seasonal Merdeka 68% offer triggered by RM68+ deposit, x4 turnover, max RM688, paid at 70% on qualifying wins; again, slots only.
- An unlimited 6.8% rebate calculated on net losses for slots; labelled x3 rollover with no stated withdrawal cap on the page I viewed.
- New register free RM30 (app only). There’s also a Playtech-exclusive RM30 version, plus a smaller RM31 free-credit window near the end of the month.
- I also spotted a sister-brand launch campaign offering free RM99 for new sign-ups over a three-day window. It’s limited-time, but it shows the kind of flash promos that appear in this ecosystem.
- Do read the small print: most offers on Intermiami888 cannot be mixed with other credits or commissions, and “bug games/free save” titles are excluded from wagering. You’ll need to clear leftover promo balances before regular withdrawals.
X33 Online Casino Malaysia promotions
- 188 free spins for new members once the first deposit lands; the spins are tied to named slot titles and credited automatically.
- A 50% welcome bonus on the first deposit, usable across slots, live casino and sports.
- A 1.1% daily rebate based on turnover, not just losses — a steady trickle for frequent play.
- VIP migration bonus RM338 if you can verify an existing VIP level from another platform.
- Frequent slot tournaments with prize pools running into the six or seven figures in ringgit, including branded events from Pragmatic Play, Spadegaming and others.

How they feel to use
I keep notes on small usability details that don’t always make the adverts. Intermiami888 keeps things simple: the cashier is clean, the promo pages spell out turnover multiples, and the slot lobby loads quickly on mobile data. Intermiami888 is easy to live with if you mostly spin and withdraw now and then.
X33 Casino is busier — in a good way if you like options. The sportsbook sits alongside live dealer rooms; eSports markets are prominent, and the site pushes tournament banners with countdowns and prize tallies. If you get bored easily and prefer to switch between football, roulette and a few spins, that breadth does make a difference.
Pros and cons at a glance
Intermiami888 – what I liked
- High, clearly tiered match bonuses (50%, 60% and 70%) with transparent turnover rules.
- The 6.8% rebate on slot losses is generous for regulars.
- Plenty of Malaysia-ready payments — FPX, Touch ‘n Go and GrabPay all worked smoothly for me.
- The BolaKing verification and names like BMM and iovation add reassurance.
Intermiami888 – what held it back
- Most perks are slot-only and can’t be stacked with other credits.
- Some promos exclude specific providers and you must clear old balances before cashing out.
X33 – what I liked
- A library that genuinely spans slots, live casino, sports, eSports and lottery.
- 188 free spins alongside a cross-site 50% welcome feels flexible.
- Daily 1.1% rebate on turnover gives a nudge back even on quiet days.
- Regular tournaments and an RM338 migration perk for established VIPs.
X33 – what held it back
- The everyday rebate is lower than the slot-loss rebate on Intermiami888.
- Because promos rotate frequently, you’ll want to re-read terms before each claim.
Banking and withdrawals
Both sites handled Malaysian payments without fuss. Deposits via Touch ‘n Go and GrabPay hit instantly on my tests, and Visa/MasterCard were as quick as the issuer allowed. Withdrawals were routine too, although promotional balances obviously add a delay because of turnover.
Intermiami888 lists FPX prominently and shows additional brand logos like iBayar on its pages; the combination suits local players who prefer e-wallets or bank transfers. X33 adds ShopeePay and Boost to the mix and talks up its AI-driven fraud filters — a nice touch for peace of mind.
My verdict – which one wins?
If you love slots and you’re motivated by match percentages, Intermiami888 nudges ahead for me. The 70% welcome (RM100 min, x5, RM388 cap) is punchy, the seasonal 68% Merdeka deal adds spice, and the 6.8% slot-loss rebate is the kind of safety net habitual spinners actually feel over a month of play. Add the BolaKing flag and the third-party test names and it feels built for value-driven slot players in Malaysia.
That said, I can’t ignore the pull of X33 Online Casino Malaysia for variety hounds. If your perfect Friday flips between Premier League bets, a few rounds of blackjack and a tournament spin on a Pragmatic Play title, the platform’s 50% welcome, 188 free spins and 1.1% daily rebate form a sensible, steady package. The RM338 migration credit is also a clever way to recognise players bringing status from elsewhere.
In short: pick Intermiami888 if your priority is bonus percentage and slot rebates; choose X33 Online Casino Malaysia if you want more ways to play and enjoy event-style tournaments.
