Oman has no legal gambling sector at all - no casinos, no licensed bookmakers, nothing for a regulator to supervise - so there is no local benchmark to compare an offshore operator against, and no local body to complain to if one stops paying.
Informational only, no operator is featured in this market.
Gambling is prohibited in Oman. No operator is listed for this market. If you are reading this from Oman the practical advice is the boring kind: do not deposit.
