Hit frequency is the share of spins that return any win at all.
RTP is how much comes back over time.
Many 'hits' return less than the stake.
Developers rarely publish it.

Short answer: Hit frequency is the share of spins that return any win at all. A slot with a 25% hit frequency pays something on about one spin in four. It says nothing about how much.

Hit frequency against RTP

RTP is how much comes back over time. Hit frequency is how often something comes back. A slot can pay often and little, or seldom and a lot, at the same RTP.

A win that is not a win

Many 'hits' return less than the stake. A 20p spin that pays 8p counts as a hit and is a 12p loss. British rules stop games celebrating those as wins.

How to estimate it

Developers rarely publish it. Fifty spins in demo mode gives a rough feel: count the spins that paid anything.
