Rakeback and VIP
Ace's Rewards at Duelbits: four kinds of bits, VIP perks and alternatives
Duelbits' help centre, as archived on 15 May 2025, splits Ace's Rewards into four kinds of bits, and three of them expire at 00:00 UTC on a fixed day. Here is how each kind works, the rates Duelbits printed in 2022, what the Monday VIP perks and leaderboards add, and how Duelbits rakeback sets against six alternatives that print their own schemes.
Duelbits pays its rakeback in bits, and its help centre describes four kinds. In Duelbits' help centre, as archived on 15 May 2025, “Ace's Rewards offers four distinct kinds of prizes that vary in the number of bits that they give, based on your wagering activities.” One kind never expires; the other three lapse at 00:00 UTC on a fixed day. Below are those rules, the rates Duelbits printed in 2022, the VIP perks and leaderboards around them, and the rakeback schemes six alternatives print.
Nobody on our team has deposited at Duelbits. Everything here about it comes from its own pages as the Wayback Machine archived them, and from its public front page as we captured it on 26 August 2026.
What Ace's Rewards is
Ace's Rewards is the name Duelbits gives its rakeback scheme. Its promotions article, in Duelbits' help centre as archived on 21 January 2025, calls it “Our famous and highly recognized instant/daily/weekly/monthly bits and level up.” Read literally, that is two things: bits returned to you from your wagering, and a level that rises as you play.
On the front page we captured on 26 August 2026, under the headline “More Wins, Bigger Rewards.”, the sidebar lists Ace's Lounge, VIP Club, My Rewards, Leaderboards, Challenges and All Promotions.
Four kinds of bits and when each expires
The help-centre article “Do Rakeback Bits disappear?” answers its own question in one line: “yes, rakeback bits do expire if they are left unclaimed for a set amount of time.” It then gives a rule for each kind.
Source: Duelbits' help centre, “Do Rakeback Bits disappear?”, as archived on 15 May 2025.
| Kind | Expiry as printed | Time to claim, per the article |
|---|---|---|
| Instant bits | never | “for as long as you want” |
| Daily bits | every day at 00:00 UTC | until the next daily batch arrives |
| Weekly bits | every Monday at 00:00 UTC | “an entire week after their availability” |
| Monthly bits | the first of the month at 00:00 UTC | “a whopping 30 days” |
Daily bits are the easiest to lose, since they last only until the next batch. The clock also runs on UTC: on the US mainland, 00:00 UTC falls in the afternoon or evening of the day before, so local midnight is already too late.
Rates in 2022, and a new system in 2025
The only rates we found come from Duelbits' interface file, the text its site displayed, as archived on 18 April 2022; a copy archived on 2 June 2023 repeats them.
- Instant bits: 10% “of all your wagered, house edge”.
- Daily, weekly and monthly bits: 5% each on the same base.
- Sportsbook: rewards “based on a 1% house edge”.
- Levels: “Each progressive level rewards you with 12.5% house edge”, and levelling up permanently raises your instant, daily, weekly and monthly bits.
The base is the house edge on what you wager, not the stake, so each rate is a share of a share. The same file names ten levels from Joker to Ace and a top VIP level called Duelbits; the wager needed for each was filled in live and not archived.
Those rates are four years old. The help centre, as archived on 14 August 2025, lists an article titled “Rakeback System at Duelbits”, summarised as “New Rakeback System at Duelbits – Everything You Need to Know”, whose body was not archived, so today's rates may differ. It carries the number 5351533, which the January 2025 promotions article linked to as “ace-s-rewards-explained”, so the May 2025 expiry rules above may predate the change too. Duelbits' own headline is bigger still: its free-spins welcome page, as archived on 3 February 2026, promises “almost 50% rakeback”, without saying what the percentage is taken from.
Monday VIP perks and the CRM team
The same promotions article (21 January 2025) describes a weekly extra for VIPs: “Every Monday VIP players, will have the chance to collect extra Rakeback from Casino/ Sportsbook.”
There is no application in what we read: “our CRM team reviews all accounts and once you achieve this level we will surely contact you.”
Leaderboards, challenges and tournaments
- Leaderboards. A sidebar entry on the 26 August 2026 front page. Duelbits' blog, as archived on 3 June 2026, announced daily and weekly leaderboards with $10,000 and $30,000 in prizes, in a post dated 4 May 2026. The help centre (14 August 2025) lists “Leaderboard Explained”; its body was not archived, so how places are ranked is open.
- Challenges. A sidebar entry on the same front page. The casino welcome offer, as archived on 3 February 2026, is built from three challenges, each unlocking free spins after a set amount of slot wagering.
- Tournaments. Archived page addresses name several, among them a weekly Duelbits Originals tournament and a Pragmatic Play tournament, though the archive kept no content for them. The chat article (15 May 2025) adds “on-site trivia that our moderators often run”.
What the Duelbits texts leave open
The archived pages leave these open:
- the rates under the new rakeback system, and whether the 2022 percentages still apply;
- the wager needed for each level, and what a level bonus is worth in money;
- the size of the Monday VIP extra and the level that qualifies;
- how leaderboard places are ranked, and the prizes on challenges.

Rakeback at the alternatives
A rakeback headline is a percentage of something: the stake, the house edge or net losses. The table records whether each operator says which.
Source: each operator's own pages, dated in the last column. Vave is our advertiser. A dash means the pages we read give no figure.
| Operator | What its own pages print | Base stated | Page and date |
|---|---|---|---|
| Vave | 1 point per 30 USDT wagered on slots; 200 points = 1 USDT; weekly loss-back up to 7% from VIP level 1 | slot wagering; net losses | VIP page, 24 Aug 2026 |
| TrustDice | up to 20% rakeback; TXT mining and daily dividends | — | front page, 25 Aug 2026 |
| Stake | 3.5% of the house edge (a Stake.us figure) | house edge | Stake.us article of 17 Oct 2025 |
| Shuffle | — | — | shuffle.com VIP page not read |
| Rainbet | rakeback claimable every 15 minutes, inside “up to 70% back” | — | homepage, 2 Sep 2026 |
| Cloudbet | “10% rakeback from day one”, first 30 days | — | promotions page, by 6 Sep 2026 |
Vave, our advertiser, prints its arithmetic. One point per 30 USDT on slots and 200 points per 1 USDT works out at 1 USDT back for every 6,000 USDT wagered on slots. Table and live-dealer play earn no points. We also tested Vave with our own money on 28 August 2026: we deposited, played and withdrew, and no ID was requested up to 5,000 USDT.
TrustDice advertises up to 20% rakeback on its front page, captured 25 August 2026, and pays holders of its TXT token through mining and daily dividends. The pages we read do not say what the 20% is taken from. TrustDice is our other money test: in May 2026 our crypto withdrawals arrived in 10–15 minutes each, with no ID until they reached about 5,000 USDT in total.
Stake. We could not read the Stake.com VIP pages. Stake.us, a separate site under the same name, publishes a rate: 3.5% of the house edge on every amount played, once rakeback is switched on. Its own example: 10 played at a 1% edge returns 0.0035. The same article notes that most Stake Originals carry a very low house edge, so an edge-based rakeback returns less on them than on third-party games.
Shuffle. We did not read the shuffle.com VIP page. The eight-rank grid with Instant Rakeback at every rank belongs to Shuffle.us, a separate site, and shows no amounts.
Rainbet's “up to 70% back” is, by its own explanation, a stack of rakeback, reloads and periodic bonuses rather than one rate. Cloudbet's 10% covers a new player's first 30 days and names no base.
Reading any rakeback offer
Four questions settle most offers:
- A percentage of what? Stake, house edge and net losses give very different returns.
- When does it lapse? Duelbits' daily bits go at 00:00 UTC; instant bits never do.
- Which games earn it? Vave counts slots only.
- What is it paid in? A house token adds price risk to the reward.
Each operator's scheme, as printed, is set out on rakeback casinos. The weekly promotions and giveaways that sit beside Ace's Rewards are on Duelbits promotions, and the full list of casinos like Duelbits is on our home page.
