proj4 was founded with a single conviction: Indonesian players deserve a world-class gaming platform that speaks their language, accepts their currency, and respects their culture. Here is how we built it.
proj4 is an internationally operated online gaming platform purpose-built for the Indonesian market. We offer a comprehensive portfolio spanning live dealer casino tables, a full-service sportsbook, thousands of slot titles, and niche verticals including sabung ayam (live cockfighting) — all under a single, unified account with one IDR balance. The platform is accessible from every major city in the archipelago: Jakarta, Surabaya, Medan, Bandung, Bali, Yogyakarta, Semarang, Makassar, and beyond, with no meaningful difference in experience based on geography.
What sets proj4 apart is not the breadth of its game library — though that library is genuinely extensive — but the depth of its localization. Every payment integration on proj4 was chosen specifically because Indonesian players use it daily: bank transfers via BCA, BRI, BNI, Mandiri, CIMB Niaga, and BSI; e-wallets OVO, DANA, GoPay, ShopeePay, and LinkAja; and QRIS for instant QR-based transactions. There is no currency conversion, no USD intermediary, and no hidden fees. When you deposit Rp 500.000, your balance shows exactly Rp 500.000.
The proj4 sportsbook was engineered around Indonesian sports culture. BRI Liga 1 matches — including fixtures from Persija Jakarta, Persib Bandung, and Bali United — are covered with both pre-match and live in-play markets from the opening whistle of the season to the final matchday. International coverage is equally thorough, spanning the EPL, La Liga, Serie A, Bundesliga, and the Champions League. For Timnas Indonesia (Garuda) matches in the Piala AFF or World Cup qualifiers, proj4 typically offers dedicated promotions and boosted odds within hours of a fixture announcement.
Our live casino operation partners with three of the industry's most respected studio providers — Evolution Gaming, Pragmatic Play Live, and Microgaming — to deliver over 100 live dealer tables running continuously, 24 hours a day. Baccarat, roulette, blackjack, Dragon Tiger, and game-show formats are all available from Rp 10.000 minimum stakes, making the experience accessible to casual players and high-rollers alike. The proj4 VIP programme extends private table access, dedicated account management, and same-day withdrawal processing to members who engage at higher volume.
proj4 treats responsible gaming as a structural commitment, not a footnote. Every member account comes with a full set of session management tools: deposit limits, session time reminders, cooling-off periods ranging from 24 hours to 30 days, and permanent self-exclusion for members who decide they need to stop entirely. Our support team — available 24/7, with native Indonesian-speaking agents — is trained to handle responsible gaming conversations with empathy and discretion. proj4 is strictly for adults aged 21 and above. We verify age as part of the KYC process and do not permit underage account registration under any circumstances.
Looking ahead, proj4 continues to invest in its platform infrastructure, expanding its e-sports coverage to include Mobile Legends MPL Indonesia and PUBG Mobile events, broadening its bandar bola (football dealer) market depth, and introducing new live casino formats aligned with player demand. The mission has not changed since day one: to be the most trusted, most locally relevant online gaming platform available to Indonesian players — one that earns confidence through transparency, speed, and genuine care for every member's experience.

Adults Only — 21+. proj4 is strictly for players aged 21 and above. By registering an account, you confirm that you meet this minimum age requirement. If you or someone you know is struggling with gambling-related harm, visit our Responsible Gaming page for support resources.
Six principles guide every decision proj4 makes — from the games we list to the payment methods we integrate and the support we provide.
proj4 publishes its game provider certifications, RTP ranges, and bonus terms in plain language. We do not bury wagering requirements in fine print. What you see in the promotions section is exactly what applies — no post-registration surprises.
Our product team includes analysts who follow BRI Liga 1, track Indonesian e-sports rankings, and understand the cultural significance of seasonal events from Idul Fitri to Nyepi. Promotions are timed to moments that matter to Indonesian players, not recycled from European market calendars.
Deposits credit in seconds. Withdrawals to BCA, BRI, BNI, Mandiri, and major e-wallets process within minutes during standard WIB banking hours. For VIP Elite members, same-day withdrawal is guaranteed regardless of the processing window. We treat your time as valuable.
Responsible gaming at proj4 is not a compliance checkbox — it is built into the core account infrastructure. Deposit limits, session time alerts, cooling-off periods, and self-exclusion are all accessible in one click from account settings. Our support team is trained to assist any member who feels gambling is becoming a problem.
Player accounts and financial data are protected by 256-bit TLS encryption, multi-factor authentication options, and a strict no-storage policy for banking credentials. Regular third-party security audits validate our infrastructure. Your data is never sold or shared with third parties outside of mandatory regulatory processes.
proj4 only integrates game studios whose content has been certified by independent testing laboratories including eCOGRA and GLI. Every new product vertical — from the e-sports book to the sabung ayam arena — goes through a quality review before it reaches members. We would rather launch fewer features well than many features poorly.
