K138 glossary

Main wallet: the central balance for deposits and withdrawals. Product wallet: the balance a lobby can use; transfer into it before playing. Rollover: qualifying bets needed before bonus money can be withdrawn, normally (deposit + bonus) × the stated multiple. Valid bet: a settled bet that counts; voided, drawn and both-sides bets do not. Rebate: a daily percentage of valid bets, 0.35% to 1% depending on product and tier, paused while a bonus is active. Net loss: win/loss minus rebate paid minus bonuses claimed. Cap: the most an offer can pay.
Bonuses

Frequently asked questions
What is the difference between rebate and cash back on K138?
Rebate is paid daily on valid bets, win or lose. Weekly VIP cash back is paid on net loss for VIP members only.
Why do some bets not count as valid bets?
Draws, voided bets, both-sides bets and sports selections below 1.50 decimal odds carry little or no risk, so they are excluded from rebate and rollover.
