Halloween spin-to-win popups

Two to three weeks before October 31 for costume, candy and decor stores; one week is enough elsewhere. End them the day after Halloween.

Choose the dose: a full theme suits playful brands, a single seasonal accent such as a color or an icon keeps a premium store on-brand.

Three to six prizes you are happy to give, with the cheapest one (often free shipping) as the most likely win. Avoid “no prize” slices: a visitor who gives an email and wins nothing rarely buys.

They can if the styling looks like a casino. A wheel in the brand’s own colors and type, with modest prizes, reads as playful rather than cheap.
