Subsino of Taiwan has launched two new casino slot games.

Treasure Island 1700 is a five-reel, 25-line game with state-of-the-art graphics that create a 3D effect, while Tomb Crasher has a locking feature.

Some of the nine reels lock when the same symbol appears in each corner, leaving the unlocked reels to spin for high wins.

"With 25 years’ experience in producing gaming machines, we know what players demand," said Subsino’s Hunter Wu. "We design games to create more profit for our customers."
