Land 3 or more Gold Star scatters anywhere on the reels to trigger 10 free spins. Retrigger during the bonus to earn up to 20 free spins total.
Every spin contributes to four jackpot tiers — Mini, Minor, Major, and Grand. The Grand Jackpot has no cap and keeps growing until someone hits it.

Diamond Tycoon is a high-volatility video slot available exclusively at ji8888, designed with Filipino players in mind. Set against a backdrop of glittering gemstones and vault-cracking wealth, the game puts you in the shoes of a diamond magnate building an empire one spin at a time. With 243 ways to win across a 5×3 reel grid, there's no need to worry about fixed paylines — matching symbols anywhere on adjacent reels from left to right counts as a win.
What sets Diamond Tycoon apart from the hundreds of other slots at ji8888 is its combination of a genuinely high RTP of 97.1% and a progressive jackpot that has no ceiling. The game has produced some of the biggest single-session payouts in ji8888's history, including a ₱4.85 million Grand Jackpot hit by a player from Manila earlier this year.
Getting started is straightforward. Log in to your ji8888 account, navigate to the Slots section, and search for Diamond Tycoon. Set your bet size — anywhere from ₱5 to ₱25,000 per spin — and hit the spin button. The game's autoplay feature lets you set between 10 and 1,000 automatic spins with optional win/loss limits, which is handy if you want to let the reels run while you watch a PBA game on the side.
The core mechanic is simple: land matching symbols on adjacent reels starting from the leftmost reel. The Diamond Wild substitutes for all symbols except the Gold Star scatter, and when it lands, it cascades down the reel to fill the entire column — giving you a much better shot at completing multiple winning combinations in a single spin.
The most exciting part of Diamond Tycoon is the Free Spins bonus round. Land three or more Gold Star scatter symbols anywhere on the reels and you'll trigger 10 free spins. During the bonus, all Diamond Wilds become sticky — they stay in place for the duration of the free spins, which can lead to some seriously stacked reels by the end of the round. If you land three more scatters during free spins, you retrigger the bonus and add another 10 spins, up to a maximum of 20.
The Tycoon Multiplier Mode is a random base-game feature that activates without warning. When it triggers, a multiplier of 2×, 3×, or 5× is applied to your next winning spin. It's not something you can buy or predict — it just shows up, which makes every spin feel like it could be the one.
Diamond Tycoon features a four-tier progressive jackpot: Mini, Minor, Major, and Grand. A small percentage of every bet placed on Diamond Tycoon across all ji8888 players feeds into these jackpot pools. The Grand Jackpot is the one everyone's chasing — it's currently sitting above ₱12 million and climbing. Any spin at any bet level can trigger a jackpot, though higher bets do increase your probability of hitting the upper tiers.
ji8888 processes jackpot payouts directly to your account balance, and from there you can withdraw to GCash, PayMaya, BPI, BDO, or Metrobank. Most jackpot withdrawals are processed within the same business day, with GCash transfers typically completing in under an hour.
