Dolphin: a purple dolphin, nine lines and a pearl behind one of two clams

The pearl was behind the right clam. That's the last screenshot of Dolphin on 3Win8: a win of 0.04 turned into 0.08 because the right-hand shell opened on a glowing pink pearl. It's the part of this game I'd actually remember, because the base game is about as plain as a slot gets.

Nine lines of cartoon fish

Nine lines, cartoon sea creatures in blue tiles, and a paytable that fits on one page. The purple dolphin pays 1,000 for five, 200 for four, 50 for three. The clownfish pays 400, the octopus 150, the seahorse 100, the turtle 75, the pufferfish 50 and a gold coin 20. There are no card letters at all, which is unusual.

A treasure chest with BONUS written across it appears on reels 1 and 5 in the first game shot. The old page talked about an open-shell scatter with 15 free spins and tripled wins. I didn't see a shell scatter on the reels or the paytable page, and no screen explains the chest, so I'd check the ? button.

Wins and the double game

When you win, every symbol not in the win turns grey, and the AUTO button becomes a pink DOUBLE. Here three gold coins paid 0.04 on a 0.02 line bet.

Press DOUBLE and the reels are replaced by a reef with two closed clams. Under them are LEFT x2 and RIGHT x2 buttons, and at the bottom BET, WIN and TAKE.

After the pick an R appears in the bar at the top, which looks like a history of results. Guess wrong and you'd lose the 0.04. It's a coin toss with a nice animation.

At 0.10 a line all nine lines cost 0.90. At 0.02 it's 0.18. There are no jackpot boxes in this one.

The fancier sea slots on 3Win8 are Dolphin Reef and Crystal Waters. Captain's Treasure is the other 9-liner. The full list is on the 3Win8 games page, and the 3Win8 overview covers accounts. You can get a 3Win8 game ID through a provider.
