A 2x wild multiplier during free spins will usually pay a lot more than a multiplier landing during the main game. If the slot has a wild symbol, check if it only substitutes for symbols, or if it also expands, sticks, or walks across the reels. These replace ordinary symbols with cash or multiplier values, then lock your board for a set number of spins while you try to fill the remaining spaces before the counter runs out.
