About Oddsmaker
Oddsmaker (often stylised OddsMaker) is an online gambling operator offering a sportsbook, casino games and poker. The brand has roots dating back to the late 1990s and has promoted high-value welcome and reload bonuses.
The operator claims a Curacao-style licence and markets itself to an international player base. Despite a long presence on the web, the site’s reputation among independent reviewers and player communities is poor due to frequent payout complaints.
Marketing emphasises a broad market line-up and generous promotions. However, multiple independent review sites and watchdog listings have documented cases of delayed or refused payouts and problematic account closures.
Reputation and Player Experience
While some players report that the site’s interface and markets are competitive and promotions initially appear attractive, many have experienced issues when attempting withdrawals.
Reports collected across review platforms indicate customer support can be slow to respond or unhelpful where withdrawal disputes are concerned. A number of complaints remain unresolved for long periods.
The cumulative player feedback leads to significant trust concerns. Several industry sites have effectively blacklisted the brand, warning prospective customers not to deposit funds.
Given the sustained volume of payout-related complaints, exercise extreme caution – do not treat advertised bonuses as guaranteed value.
Reported Issues: Payment delays/non-payment (multiple reports) | Typical Experience: Risky/Unreliable | Jurisdiction: Claims Curacao | Timeframe: Active (since ~1998)
‘Attractive bonuses but a very risky site — many players report not receiving withdrawals.’ — Industry watchdog summary
Bonuses and Promotions
Oddsmaker advertises large welcome bonuses (commonly a 100% deposit match) and ongoing reload and VIP promotions. Exact amounts and wagering requirements vary by promotion and over time.
Although bonus values can appear generous, players should be cautious: reported issues with account closures and payment refusals may prevent realization of bonus winnings.
Casino Welcome Bonus
Typically advertised as a 100% deposit match (examples of marketing show caps such as $1,000). Bonus terms, wagering requirements and eligible games are set in the site’s T&Cs and may restrict cashout until conditions are met.
Sportsbook Welcome Bonus
Promoted sportsbook bonuses frequently include a 100% match or a free-bet offer. Wagering rules and market eligibility apply — read terms carefully. Historical reports indicate issues when attempting to withdraw winning funds.
Reload / Ongoing Promotions
The site has historically offered periodic reloads, odds boosts and VIP incentives. Availability and value change frequently and are governed by promotional terms.
Referral and VIP Offers
Referral bonuses and VIP-tiered incentives have been part of the marketing mix. VIP perks are often used to retain high-value players but do not mitigate documented payment risk.
Occasional slot races and tournament-style promotions have been listed on the operator’s promo pages. Participation is subject to promotional rules and eligibility.

How Oddsmaker Bonuses Compare
Oddsmaker’s headline bonus amounts are competitive on paper, especially for high rollers seeking large match bonuses.
However, compared with reputable licensed operators, Oddsmaker scores poorly on reliability and payout fairness — a key metric when valuing a bonus.
Players should prioritise operators with strong regulatory oversight and a history of reliable payouts over higher nominal bonus values.
Recommendation: Do NOT deposit significant funds. Bonuses are not worth the risk if the site has a history of payout and dispute issues.
VIP and Loyalty Programs
Oddsmaker advertises VIP benefits for high-volume players, typically including enhanced bonuses, dedicated support and tailored promotions.
Exact VIP structure and benefits are not transparent and may be used as retention tools for higher-value customers.
Given the documented payout issues, VIP benefits are insufficient to offset the risk of non-payment or account closure.
Banking Methods
The site lists several deposit and withdrawal channels in its help and terms pages. Accepted methods have historically included major cards, bank wire and various e-wallets and cryptocurrency options; availability varies by jurisdiction.
Deposits
Oddsmaker accepts common deposit methods (Visa, Mastercard, Bank Wire, E-wallets, Cryptocurrency). Minimums and processing times depend on chosen method and the player’s country. Promotional eligibility may require specific deposit types.
| Deposit Method | Min. Deposit | Max. Deposit | Deposit Now |
|---|---|---|---|
| Visa / Mastercard | $10 | $10,000 | Deposit with Card |
| Bank Wire | $100 | $50,000 | Deposit with Bank Wire |
| E-wallets (PayPal/Skrill/Neteller) | $10 | $10,000 | Deposit with E-wallet |
| Cryptocurrency (Bitcoin, Ethereum) | $5 | Varies | Deposit with Crypto |
Withdrawals
Multiple player reports across independent sites cite slow withdrawals, withheld funds and account closures when attempting to cash out. Watchdog pages list numerous complaints and, in several cases, alleged non-payment.
Players should be prepared for lengthy processing times and potential disputes; keep records of all communications if you attempt to withdraw funds.
| Withdrawal Method | Min. Withdrawal | Max. Withdrawal | Timeframe |
|---|---|---|---|
| Visa / Mastercard | $20 | $5,000 | 3-10 days (reported delays) |
| Bank Transfer | $100 | $50,000 | 5-15 days (reported delays) |
| E-wallets (Skrill/Neteller) | $20 | $10,000 | 1-7 days (reported delays) |
| Cryptocurrency (Bitcoin, Ethereum) | $10 | Varies | Up to several days (reports of delays) |
Casino Offering
Oddsmaker operates a casino lobby with slots, table games and specialty titles. The casino experience is integrated with the sportsbook account system.
Game providers and RTP details are not consistently transparent in third-party reviews; some sections appear to run on a proprietary platform rather than only third-party aggregators.
Slots
The slots selection includes classic reels and modern video slots. Specific provider names and progressive jackpot details are not consistently documented in public reviews.
Players should treat slot promotions cautiously because reported account closures or withheld funds can prevent successful cashout even after meeting wagering requirements.
Selection varies; expect classic reels, branded and modern video slots.
Progressive jackpot titles may exist but public details are limited; verify payouts and terms on a per-game basis.
Some games appear targeted at higher-stakes players; RTP and volatility information should be checked where available.
Play options and bet ranges depend on game and player jurisdiction.
Table Games
Standard table games (blackjack, roulette, baccarat) and video poker variants are reported. Live dealer availability is unclear or limited in current public materials.
Live dealer sections are not well-documented; where present, tables are typical of small or proprietary live studios rather than major live-dealer providers.
Poker
Poker offerings have been part of the platform historically, with cash games and tournament listings subject to player volumes and regional availability.
The poker ecosystem is less transparent than larger, regulated poker networks; player liquidity and prize guarantees may vary.
Live Dealers
Live dealer offerings are not prominently documented; availability may be limited compared with leading casino brands.
Where live tables are offered they may run on smaller or proprietary studios rather than major third-party providers.
Casual Games
Some casual games and specialty titles (scratch cards, bingo-style games) may be present, but details are inconsistent across sources.
Oddsmaker Sportsbook
Oddsmaker’s sportsbook covers a broad range of global sports and markets, with pre-match and live betting lines.
Market depth can be good for major sports and events, including football, basketball, tennis and combat sports.
However, account-level restrictions and payout problems reported by users undermine the practical value of the sportsbook for many customers.
Sports
Coverage typically includes football (soccer), American football, basketball, baseball, tennis, boxing/MMA and others — live betting markets are offered on selected events.
Odds and markets may be competitive, but account-level restrictions and payout problems reported by players undermine the practical value of the book.
Betting types include singles, accumulators and handicaps, with live in-play options for some events.
eSports
eSports markets have been featured at times (common titles such as CS:GO, League of Legends, Dota), depending on the operator’s current product mix.
League of Legends and CS:GO frequently appear in coverage when eSports are offered, alongside multi-market betting options.
eSports liquidity and market coverage may fluctuate with operator focus and player demand.
Virtual Sports
Virtual sports options may be available; specifics are not consistently documented in third-party reviews.
Virtual products typically include simulated football, horse racing and niche quick-play options subject to availability.
Mobile Experience
Oddsmaker provides a mobile-friendly site and occasionally native apps, allowing betting on sportsbook and casino products via mobile browsers.
User reports indicate the interface can be functional, but trust and payability concerns are by far the biggest practical issues rather than mobile UX.
Safety and Security
Oddsmaker claims Curacao-style licensing but this jurisdiction offers limited player protections compared with stricter regulators. Independent watchdogs caution users due to the operator’s history of disputes.

Final Verdict
Oddsmaker offers a broad product mix and historically large promotional offers, but the operator’s long record of complaints about withdrawal delays and alleged non-payment is a major red flag.
We recommend avoiding depositing funds with Oddsmaker. If you already have an account, exercise caution, minimise balances, and document all communications with support; escalate disputes through payment provider or consumer protection channels if necessary.
