The UU Slots Aqua Reef Demo
A shell pick opens the Free Game in Aqua Reef, an underwater slot that pays on 25 fixed lines across a 5×3 grid. Pearl scatters set it off.
The golden fish Wild carries the rest of the design. It doubles the wins it joins, and its own pay row is the strongest in the table. Volatility is at the top of UU’s 5-point scale.
How to Play
RTP
Aqua Reef’s RTP is 96%, and the Free Game starts from the pearl scatters. Its 25 lines count from reel 1 rightwards, and each pays out the biggest combination it holds.
Golden Fish Wild
The golden fish stands in for any symbol bar the scatter and doubles the wins it is part of. A line of five golden fish makes the top pay, and since every Wild doubles its line, the top of the paytable belongs to that one fish.
Pearl Scatters
Any 3 or more Free Game Scatters, the pearl in a pink shell, trigger the Free Game wherever they land. They pay as well, and the pay jumps from 0.8x for four pearls to 20x for five.
Shell Pick Free Game
The feature opens on a PICK 1 SHELL screen, and the shells there hold free games and multipliers, up to 33 games or x15. In the rules illustration, a Free Games counter and a Multiplier counter appear above the shells, which show values such as 15, 10, x5, and x8. Winning the bonus again during the Free Game adds 15 additional free games. Once the feature has ended, the free game counter resets to its initial value.
