Casino > Spilleautomater > Spectrum Spectrum Game Rules All wins are paid for combinations of the same symbol, from left to right and right to left, on each of 10 winning lines. On active line only higher win is paid. Each new game costs one stake. WILD substitutes for any other symbol. WILD symbol expands and holds the whole reel, then awards with one free re-spin. WILD is not a winning symbol. If a new WILD appears during a re-spin, it expands and holds in place together with any previously expanded WILD for another re-spin, up to 3 re-spins. WILD may occur on reels 2, 3 and 4 only. Re-spins are played at the same bet as the round activating the re-spins. The theoretical return to player for this game is 96.30%.
