Asian Handicap
A popular betting format in Asia where one team is given a virtual head-start or deficit to level the playing field. Asian handicap eliminates the possibility of a draw by using half-goal increments, making it especially popular for football betting on leagues like the English Premier League and PBA All-Filipino Cup.
Over-Under (Totals)
A bet on whether the combined score of both teams in a game will be over or under a number set by the bookmaker. For example, if the total for a PBA game is 185.5 points, you bet whether both teams will score more or less than that combined.
Odds Formats
Betting odds can be displayed in three main formats: Decimal (1.90 means you get ₱190 back for every ₱100 bet), Fractional (9/10 format used in UK markets), and American/Moneyline (+100 or -110). phpopen defaults to decimal odds for Filipino players.
RTP (Return to Player)
The long-term percentage of wagered money a slot machine or casino game pays back to players. A slot with 96% RTP returns ₱96 for every ₱100 wagered on average over many thousands of spins. Higher RTP is generally better for players.
House Edge
The mathematical advantage the casino holds over players in any given game. In European Roulette the house edge is 2.7%; in blackjack with perfect strategy it can drop below 0.5%. Understanding house edge helps you choose games wisely.
Wagering Requirement
Also called rollover, this is how many times you must wager a bonus amount before you can withdraw it. For example, a ₱500 bonus with a 20x wagering requirement means you must place ₱10,000 in total bets before the bonus converts to real cash.
Live Dealer Casino
Games broadcast in real time from a professional studio with human dealers. You see the actual cards being dealt or the roulette wheel spinning via HD stream. Evolution Gaming powers most live dealer tables on phpopen, covering baccarat, blackjack, roulette, and game shows.
Slot Volatility
How often and how much a slot pays out. Low-volatility slots pay small amounts frequently — ideal for long sessions with a smaller bankroll. High-volatility slots pay large amounts rarely — suited for players chasing the big jackpot with patience and a bigger budget.
Progressive Jackpot
A jackpot pool that grows every time a player bets on a linked network of games and no one hits the top prize. These jackpots can reach millions of pesos across connected machines at multiple online casinos simultaneously, with a single lucky spin deciding the winner.
Cashback
A loyalty or promo feature where the casino refunds a percentage of your net losses over a defined period — usually weekly. For example, a 10% cashback on ₱2,000 net losses returns ₱200 to your account. phpopen Loyalty Club members receive cashback based on tier level.
Bonus Buy (Feature Buy)
An optional feature in certain slot games that lets you pay a premium — typically 50–100x your stake — to immediately trigger the bonus round or free spins feature, skipping the base game. Not available in all jurisdictions; check each game's rules.
KYC (Know Your Customer)
A mandatory identity verification process required by PAGCOR regulations. You'll need to submit a valid government-issued ID (UMID, PhilSys, or passport) and proof of address before large withdrawals can be processed. Completing KYC early speeds up all future payouts.
