015 reels, 243 ways
Thunderstruck II has 5 reels and 3 rows with 243 ways: matching symbols on neighbouring reels from reel 1, in any row, pay. Two of a kind are not enough — wins start at three.
The gods pay most — 
Thor, 
Odin, 
Loki and 
Valkyrie — then 
Valhalla and the 
longship, and the icy letters 
A to 
9.
02The Wild and Wildstorm
The 
Thunderstruck II logo is the Wild: it substitutes for every symbol except the hammer and doubles wins it is part of. At random, Wildstorm can strike and turn up to five reels fully Wild.
03Hammers
Three or more 
hammers anywhere open the Great Hall of Spins. Hammers also pay on their own: 2, 3, 4 or 5 pay 1×, 2×, 20× or 200× the bet.
