How icb138 Tier Progression Works
Your tier at icb138 is determined by your monthly activity score, which accumulates from deposits, wagers, and completed plays across all game categories. We do not require a minimum deposit amount to join; even modest regular activity moves you toward higher tiers. Each tier unlocks a new cashback rate—Bronze members receive a baseline percentage, while Diamond members enjoy our highest rate. The tier resets monthly, so your status is recalculated on the first day of each calendar month based on the previous month's activity.
Tier benefits include:
- Cashback credited directly to your account balance on the first business day of the following month.
- Exclusive promotional offers sent via email and your account dashboard.
- Priority support queue—higher tiers receive faster response times from our English-language team.
- Birthday bonus offers during your birth month, regardless of tier.
- Seasonal event bonuses during Liga 1 playoffs, Piala AFF tournaments, and major holidays.

Bronze members receive a baseline rate, while Diamond members receive our highest rate. Cashback is calculated every Sunday and credited by Tuesday morning.
Eligible wagers include all plays on our live-dealer tables (blackjack, roulette, baccarat, Dragon Tiger), slot games (Aviator, Sweet Bonanza, Gates of Olympus, Fortune Tiger, Mahjong Ways), and sports markets. Certain promotional plays or bonus-funded wagers may have different cashback rates; these are noted in the promotion terms when you claim a bonus.
