Twin reels
At least two adjacent reels are synchronised.
An introduction to NetEnt's Twin Spin and its linked-reel feature.

Twin Spin combines a five-by-three grid with 243 ways to win. The key distinction is adjacent twin reels that begin linked on every spin.
The linked group can expand to three, four or five reels. This changes which reels show the same symbols, rather than creating a separate promise of a payout.
Matching symbols are evaluated from the leftmost reel across adjacent reels. The game's ways-based structure should not be confused with choosing individual fixed paylines.

Imagine two adjacent reels displaying the same symbol arrangement. If the linked group expands, more reels share that arrangement. The relevant question is still whether an eligible matching combination starts from the left.
Wild symbols appear on reels two through five according to the publisher's description. Consult the particular game's information panel for symbol values and the full evaluation order.
These points separate the choices and conditions that are easily confused.

The linked group may cover more of the five-reel grid.
Combinations use adjacent reels rather than a chosen drawn line.
Do not confuse Twin Spin with similarly named sequels.
Separate linked-reel behaviour from payout values.
Follow the evaluated symbols without assuming a guaranteed pattern.
