U388 runs 4D through a single lottery platform called eKOR. One lobby, one provider, and inside it a list of the draws Malaysian 4D players already know: Magnum, Sports Toto, Da Ma Cai, Cash Sweep, STC 4D, Singapore Pools and Lucky Hari Hari. Bet types cover iBox, 4D, 5D and 6D. Results update in the lobby after each draw.
So the coverage is there. The catch is money: eKOR is excluded from U388’s promotions in Malaysia, and lottery bets do not count towards any bonus turnover. No lottery rebate rate is published either. In practice, 4D on U388 is bonus-dead. If you want value from promotions or rebates, it comes from slots, live casino or sports, not from your 4D numbers.
eKOR gathers the draws into one place rather than sending you to separate lobbies per operator. Magnum, Sports Toto and Da Ma Cai are the licensed 4D operators on the peninsula, so those are the names you know from the counter. Cash Sweep and STC 4D come from East Malaysia, and Singapore Pools is Singapore’s operator. Lucky Hari Hari appears as its own option in the list.
That breadth is the genuine appeal here. At a shop counter you buy from whichever operator that outlet carries. In the eKOR lobby you pick the operator from a list, then the number and the bet type, without changing wallets or providers.
One thing to be clear about before you fund anything: U388 is not an agent, partner or licensee of any of these operators. It is an offshore site accepting bets on their draw results. You are not holding an operator’s ticket, and the operator has no relationship with your U388 account. Whatever the outcome, everything about the bet, the price and the payout is settled between you and U388 inside eKOR. If holding a ticket issued by a licensed operator matters to you, buy it at the counter instead.
Most of these terms come from the shop, not from U388, so the mechanics work the way 4D players already understand them. The table below is general 4D knowledge, not a U388 price list.
| Bet type | What you pick | Trade-off |
|---|---|---|
| 4D straight | One four-digit number in exact order | Highest payout per ringgit, single winning combination |
| iBox | One four-digit number, all permutations covered | Many more ways to win, lower payout per permutation |
| Big and Small | Which prize categories your number plays for | Small covers fewer prize positions at a higher rate per position; Big spreads across more positions for less each |
| 5D | A five-digit number | Usually pays on partial matches as well as the full number |
| 6D | A six-digit number | Partial matches typically pay as well, at lower rates |
| Lucky Hari Hari | A named option inside eKOR | Rules and prices are shown inside the lobby |
The one worth understanding properly is iBox. A straight bet on 1234 wins only when the draw produces 1234. An iBox bet on the same digits wins on 4321, 2143, 3412 and every other arrangement. With four different digits that is 24 permutations, so your chance of a hit rises sharply. In general the payout per permutation drops in proportion, which is why iBox suits players who like their digits but not the exact order. Repeated digits shrink the number of permutations, so a number like 1223 behaves differently from 1234.
Big and Small work as they always have: Small pays more per position but plays for fewer prize positions, while Big reaches further down the prize list for a smaller rate. Neither is smarter than the other; they are different shapes of the same bet.
U388 publishes no payout table and no maximum payout for any of this. Prices appear inside the eKOR lobby, and that is the only place to see them. Check the price on the ticket screen before you confirm, because you cannot compare it in advance from anywhere else on the site.
Funding works the way it does for every other provider on the platform. Deposits and withdrawals move through the Main Wallet only, and each provider keeps its own game wallet, so money has to be moved across before you can bet.
Leftover balance in the eKOR wallet can be moved back to the Main Wallet at any time. Do that before you request a withdrawal, because withdrawals are processed from the Main Wallet and nothing sitting in a game wallet counts as available. The rules on minimum deposits, name matching and the 1x turnover that applies to every deposit are worth reading once on the deposit and withdrawal guide before your first transfer.
If a single lobby covering Magnum, Toto, Da Ma Cai, Cash Sweep, STC and Singapore Pools is what you came for, the eKOR lottery section sits behind a standard account.
Nothing below is a surprise once you know it, but all of it costs you something if you find out afterwards.
The honest conclusion: treat 4D on U388 as a convenience product, which is also how it reads in our full review. It puts seven draw sources in one place and takes your bet without a trip to a counter. It does not participate in the rewards side of the platform at all, so if you split your bankroll, the promotion-earning half belongs somewhere else.
If you want something quick between draws, the lottery lobby is not the place. The Fast Game section is where Aviator, the Spribe mini games and the arcade titles sit, and unlike 4D those do earn the slot-level rebate.
For everything about bonus mechanics, claiming through the Rewards page and which providers each offer excludes, the promotions rules are covered separately. The single line to carry away from them here is the one already stated above: eKOR is on the exclusion list, so 4D and bonuses never meet.
