The ACE66 welcome bonus arrives in two versions. Slots and fishing players get 100% of their first deposit up to RM300, while Mega888 players get 150% up to RM300 on a different kind of requirement. After that, eight deposit offers sit in the promotion list: two welcomes, three daily reloads and three unlimited top-ups, each with its own multiplier. The multiplier decides whether an offer suits you, so every figure below is written out in ringgit.
Each offer starts at a RM30 minimum deposit. The cap is the most bonus money the offer will pay, and the requirement is what has to happen before the promotion closes and your balance becomes withdrawable.
| Offer | How often | Bonus and cap | Requirement | Worked example |
|---|---|---|---|---|
| 100% Welcome (Slots & Fishing) | Once, new members, first promotion application only | 100%, up to RM300 | 12x turnover on deposit plus bonus | RM100 + RM100 = RM200, x12 = RM2,400 of bets |
| 150% Welcome (Mega888) | Once, new members | 150%, up to RM300 | 8x winover | RM30 + RM45 = RM75 credit, target RM675 |
| 50% Daily Reload (Mega888) | Once a day | 50%, up to RM500 | 6x winover | RM30 + RM15 = RM45 credit, target RM315 |
| 20% Daily Reload (Slots & Fishing) | Once a day | 20%, up to RM300 | 10x turnover | RM100 + RM20 = RM120, x10 = RM1,200 of bets |
| 10% Daily Reload (Sports & Esports) | Once a day | 10%, up to RM300 | 8x turnover | RM100 + RM10 = RM110, x8 = RM880 of bets |
| 10% Unlimited (Mega888) | Unlimited | 10%, up to RM500 | 3x winover | RM30 + RM3 = RM33 credit, target RM132 |
| 10% Unlimited (Slots & Fishing) | Unlimited | 10%, up to RM300 | 8x turnover | RM110, x8 = RM880 of bets |
| 5% Unlimited (Sports & Esports) | Unlimited | 5%, up to RM100 | 8x turnover | RM100 + RM5 = RM105, x8 = RM840 of bets |
Two caps are worth doing the arithmetic on before you claim. Take the 100% welcome to its ceiling with a RM300 deposit and you hold RM600, which at 12x means RM7,200 of qualifying turnover. Take the Mega888 welcome to its ceiling with a RM200 deposit and the RM300 bonus gives RM500 of credit with a balance target of RM4,500. Both are large numbers for a first session, so a smaller deposit on the same offer keeps the requirement within reach.
The 10% unlimited slots and fishing offer runs on all slot providers except Mega888, Habanero and KingMidas. Mega888 has its own unlimited offer in the same list, with a lower multiplier.

For the slots, fishing, sports and esports offers, the requirement is turnover: the total value of the bets you place. Wins and losses along the way do not change what you owe. A RM120 balance at 10x needs RM1,200 of bets, and you can reach that with sixty RM20 spins or six hundred RM2 spins.
The Mega888 offers work as winover instead. In general, a winover target is a balance figure rather than a bet count: the requirement is met only when your account balance reaches the whole credit plus that credit multiplied by the stated number. Losing bets bring you no closer.
| Mega888 offer | Deposit | Credit after bonus | Requirement | Balance target |
|---|---|---|---|---|
| 150% Welcome | RM30 | RM75 | 8x winover | RM675 |
| 50% Daily Reload | RM30 | RM45 | 6x winover | RM315 |
| 10% Unlimited | RM30 | RM33 | 3x winover | RM132 |
Read those three rows next to each other and the pattern is clear. The headline percentage and the difficulty of the requirement move together. The 150% welcome hands you the most credit but asks your RM75 to become RM675, while the 10% unlimited offer asks RM33 to become RM132. If you want bonus credit on Mega888 with the shortest route out, the unlimited offer at 3x is the lighter commitment.
Claiming changes how your account behaves until the promotion closes, so it helps to know what changes.
Game types matter as well. On the slots and fishing offers, bets on table, arcade, scratch and video poker games do not count toward turnover, so a session spent on those makes no progress. On the Mega888 offers, the bonus money is for slots inside the app, and winnings from other game types are void. Bets on Ocean King and Fish King are not accepted at all, and winnings from them are not honoured.
The common rules apply across all of them. One claim per member, and the welcome bonus only on your first promotion application. Multiple accounts void everything. Hedging, opposite bets, draws and rejected or invalid bets do not count. Offers are not combinable with each other, and ACE66 can change or end a promotion without notice.

Pick from what you play and how soon you want to cash out, not from the biggest percentage. You are never obliged to claim anything: a plain deposit with no promotion attached leaves the whole lobby of slots, live tables, fishing and sports open and your balance free to withdraw.
Your first deposit decides which welcome offer you can apply for, so choose the one that matches the games you play.
Bets wagered under an active promotion’s turnover are excluded from the rebate. That single rule is what makes the choice above a real choice rather than a formality. A bonus gives you extra credit with a condition attached. The rebate gives you a small percentage of qualifying bets back every day, with no turnover and no minimum payout, credited by 4 pm.
For a player putting serious volume through the slots or the sportsbook each week, the arithmetic often favours the plain deposit. RM10,000 of qualifying slots turnover returns RM50 at Bronze 1 and RM90 at Diamond, and that money is withdrawable the moment it lands. The exact percentage depends on your tier and the product, which is set out in full alongside the daily cash rebate by tier.
The rescue bonus is calculated on net loss across the week, from Monday 00:00 to Sunday 23:59 GMT+8. Net loss means gross loss minus any bonus and minus any rebate received, so the figure is lower than a raw losing total.
| Weekly net loss | Reward | Cap by tier |
|---|---|---|
| RM5,000 to RM7,499.99 | RM138 | All tiers |
| RM7,500 to RM9,999.99 | RM228 | All tiers |
| RM10,000 and above | 5% of net loss | Bronze RM1,688, Silver RM2,288, Gold RM2,888, Platinum RM3,888, Diamond RM6,888 |
The caps bite earlier than the 5% headline suggests. At Bronze, the RM1,688 ceiling is reached at RM33,760 of net loss, and every ringgit lost beyond that adds nothing. The RM6,888 Diamond ceiling arrives at RM137,760. Below RM5,000 of net loss there is no rescue payment at all.
The reward carries 10x turnover before withdrawal, and Blackjack bets do not count toward it. It cannot be played on 918Kiss, Mega888, Allbet or EKOR, and it is not combinable with other offers. Eligible members are notified by Inbox every Monday between 6 pm and 8 pm, and the claim is made on the Rewards page. It is once a week only, with no backdated claims, so a missed week stays missed.

Share your referral code from the Referrals page in the member area, where your code, link and QR image sit together with your downline list and total bonus accumulated. When a friend registers with that code and deposits RM100 in total within 30 days, you receive RM20.
The RM20 carries 10x turnover, so RM200 of bets before it can be withdrawn, and the reward has to be claimed within 7 days of being issued. Both accounts must be in the same currency. The offer is limited to one per person, household, IP address, email address, mobile number, bank account or shared computer, so referring yourself from a second account voids the reward.
Separately from the deposit offers, the studios run their own campaigns inside their games: prize drops, free spin challenges, daily win events and seasonal promotions from names such as Pragmatic Play, Playtech and Microgaming. These come and go on the providers’ own schedules and their terms are set by the studio, not by the promotion list. ACE66 has no standing free spin or free credit offer of its own, so if free spins are what you are after, they come from these provider events rather than from the bonus table above.
Run through these points before you claim. The minimum deposit on every offer here is RM30, while the withdrawal minimum is RM100 per transaction, which is set out with the rest of the deposit and withdrawal limits.
