size99 is an internationally operated online betting and gaming platform built from the ground up to serve the Indonesian market. From Jakarta high-rises to Bali villas, we power a premium gaming experience for players who expect more.
size99 was founded on a straightforward observation: Indonesian players who preferred English-language betting platforms had very few genuinely localized options. Most international operators either ignored the Indonesian market entirely or offered a surface-level translation without the local payment infrastructure, cultural context, or support quality that players actually needed. size99 was created to fill that gap — an internationally operated platform that speaks the language of global gaming while staying deeply connected to the Indonesian betting experience.
From day one, our product decisions have been guided by what Indonesian players want. That meant building deep integrations with BCA, BRI, BNI, Mandiri, CIMB Niaga, OVO, DANA, GoPay, ShopeePay, and LinkAja — not as an afterthought, but as the foundation of our payments architecture. It meant building a sportsbook that prominently covers BRI Liga 1, Timnas Indonesia's Garuda fixtures, and the AFF Cup alongside the EPL, La Liga, and Champions League. And it meant building a togel (Indonesia's traditional numbers lottery) product that covers Togel SGP, Togel HK, Togel SDY, and other markets that Indonesian players follow closely — with draw schedules published in WIB.
"Our mission is simple: give every Indonesian player access to a world-class betting platform that they can trust, in a language they are comfortable with, using payment methods they use every day."
Over the years, size99 has grown from a focused sports betting operation into a comprehensive online gaming destination. Our platform today covers football betting with bandar bola (bookmaker-style) markets and deep mix parlay (multi-leg accumulator) support; a live casino powered by Evolution Gaming and Pragmatic Play Live with Indonesian-speaking hosts during peak WIB hours; a slots lobby featuring hundreds of titles from Pragmatic Play, NetEnt, Microgaming, and Pocket Games Soft; crash games like Aviator by Spribe; and niche Asian favorites including Teen Patti and Andar Bahar. All of this runs on enterprise-grade infrastructure with a 99% uptime SLA.
Trust and transparency are the twin pillars of everything we do at size99. We operate under internationally recognized gaming standards, publish RTP rates for our slot titles, use certified random number generation engines for all RNG-based games, and enforce rigorous KYC verification procedures to protect our members. Our responsible gaming program includes self-exclusion tools, deposit limits, session time controls, and clear guidance on seeking help if gambling becomes a problem — because we believe a healthy player community is a sustainable one.
Looking ahead, size99 remains committed to the Indonesian market. We are continuously expanding our esports betting coverage — particularly for Mobile Legends MPL, PUBG Mobile, and Free Fire, which are enormously popular with Indonesia's younger generation of bettors — and investing in platform performance to ensure reliable access for players from Jakarta and Surabaya to Makassar and Manado. Whether you are placing your first bet or aiming for Black Diamond VIP status, size99 is built to be the last platform you will ever need.
To provide Indonesian players with the most trusted, transparent, and feature-rich English-language online betting platform available — combining international gaming standards with genuine local market expertise, fast local payments, and around-the-clock Indonesian-speaking support.
To become the benchmark international betting brand for English-preference Indonesian players — recognized not just for our product range, but for our integrity, our player-first culture, and our unwavering commitment to responsible gaming practices across all age groups 21 and above.
Six core values guide every product decision, every support interaction, and every feature we build at size99.
Every account on size99 is protected by 256-bit SSL encryption, two-factor authentication, and real-time fraud detection. Our KYC process ensures that funds always reach the correct verified account holder — no exceptions.
Instant deposits via all major Indonesian banks and e-wallets. Most withdrawals to BCA, BRI, and BNI processed within 15 minutes. Our 99% uptime SLA means size99 is available when you need it — including during BRI Liga 1 peak match times.
size99 is more than a translated interface. We offer WIB-timed togel draws, BRI Liga 1 sportsbook coverage, seasonal promotions tied to Indonesian holidays like Idul Fitri and Nyepi, and 24/7 native Indonesian-speaking support agents who genuinely understand local player needs.
Our sportsbook delivers some of the best odds available for BRI Liga 1, EPL, La Liga, Champions League, and more. We offer full Asian handicap (voor bola) coverage, mix parlay accumulators, Over/Under, BTTS, and Correct Score markets — updated in real time throughout every match.
size99 takes problem gambling seriously. We provide self-exclusion tools, configurable deposit limits, and session time-out features. Our responsible gaming page offers links to professional support resources. We enforce strict 21+ age verification and never market to underage individuals.
Our six-tier VIP program — from Bronze through the invitation-only Black Diamond level — rewards consistent players with cashback, faster withdrawals, dedicated account managers, and exclusive tournament access. size99 members are valued partners, not just usern umbers.
Every decision at size99 traces back to four foundational principles that shape how we build, operate, and grow the platform.
We publish RTP rates, use independently audited RNG engines, and maintain clear, honest bonus terms. Players on size99 always know exactly what they are signing up for — no hidden clauses, no fine-print surprises.
size99 was designed around the Indonesian player, not retrofitted for them. Local bank integrations, WIB draw schedules, BRI Liga 1 coverage, and a support team that speaks Bahasa Indonesia natively — these are table stakes for us, not optional extras.
Enterprise-grade infrastructure, a 99% uptime SLA, and sub-second page loads on both desktop and mobile ensure that size99 never lets you down — whether you are live-betting a La Liga match or spinning slots at midnight from Surabaya.
Responsible gaming is embedded at the product level — not bolted on as a compliance checkbox. Deposit limits, self-exclusion, and time-out features are accessible from every account dashboard, and our support team is trained to identify and assist players showing signs of problem gambling.
