Betting Glossary
New to online betting? Here are 10 must-know terms explained in plain English — no jargon.
Asian Handicap
A form of sports betting popular in Asia that eliminates the draw option by giving one team a head start or deficit. It levels the playing field and typically offers better value than traditional 1X2 betting on uneven matchups.
Over/Under (Totals)
A bet on whether the combined score of a game will be above or below a number set by the sportsbook. For example: if the Over/Under for a PBA game is 185.5, you bet on whether both teams will score more or fewer than that combined.
Odds Formats
Betting odds come in three common formats: Decimal (e.g., 2.50), Fractional (e.g., 3/2), and American (e.g., +150). ah188 uses decimal odds by default — the most intuitive format for Asian players. Multiply your stake by the decimal odds to find your total return.
RTP (Return to Player)
The long-term percentage of wagered money a slot machine or casino game is expected to pay back to players. An RTP of 96% means that over millions of spins, the game returns ₱96 for every ₱100 wagered. Higher RTP = more player-friendly game.
House Edge
The mathematical advantage the casino holds over players in any given game. Baccarat has one of the lowest house edges at around 1.06% on the Banker bet — which is why it's a staple at Filipino gaming clubs and online casinos like ah188.
Wagering Requirement
Also called rollover requirement. If you claim a ₱1,000 bonus with a 20x wagering requirement, you must place ₱20,000 in bets before withdrawing the bonus funds. Always check this number before claiming any casino promotion.
Live Dealer Casino
Casino games streamed in real time with a human dealer, filmed in a professional studio. Players interact via live chat while cards are dealt or the roulette wheel spins in front of them — combining the feel of a real casino with the convenience of playing from home in Manila or Cebu.
Slot Volatility
How frequently and how much a slot pays out. Low volatility slots pay small wins often — good for casual play. High volatility slots pay less frequently but can deliver massive jackpots, like the ones on ah188's progressive slot titles.
Progressive Jackpot
A jackpot that grows continuously as players across a network wager on linked games. A small fraction of each bet feeds the jackpot pool until one lucky player triggers it. ah188 features several progressive jackpot slots with pools that can reach ₱5 million and beyond.
Cashback
A promotion where a percentage of your net losses over a defined period is returned to you as bonus or real cash. ah188's Silver and Gold loyalty tier members receive 10%–20% monthly cashback, softening losing streaks and keeping play sustainable.
