Coming soon, Twin Spin
NetEnt has released a new YouTube clip with a new slot game, Twin Spin. They have not yet released a date, but I expect it will be released in November 2013.
From what I can make out, the new game has 243 ways instead of paylines.
The reason they must have called it Twin Spin is because 2 reels will always spin together, always stopping on the same symbols, which reels is random.
And what I can see is that the feature appears random and will make 3, 4 or even all reels spin the same.
Below is the YouTube clip of Twin Spin.
