The number of free spins tells you how many times the reels turn. The RTP of the slot tells you what those spins are worth. Most free spins pages ignore the second number entirely, which is how 100 spins on a weak game gets advertised as a better deal than 50 on a strong one.
Every offer below runs on a slot returning at least 96%, which is above the 95.88% average across the games we track. Each card shows the game, its published RTP and its volatility, so you can compare offers on what they actually return rather than on the headline count.

Why the Difference Adds Up
Take 50 spins at 20p, which is £10 of play. On a slot returning 96.5%, the expected return is £9.65. On one returning 94%, it is £9.40. A 25p gap sounds trivial, and on a single offer it is.
It stops being trivial once wagering is applied. Winnings from free spins usually have to be played through 30 or 40 times before they can be withdrawn, and every one of those spins is subject to the same RTP. A two point difference compounds across hundreds of spins into a real gap in what reaches your balance.
A Caution About RTP Versions
Providers ship many slots in more than one configuration. Pragmatic Play, for example, offers builds of the same game at 96.50%, 95.50% and 94.50%, and the casino chooses which one to run. The figure we list is the published default, so check the RTP stated in the game information panel once the spins load.
Our high RTP slots page ranks every game we track by return, whether or not an offer is attached to it. To browse offers by size instead, see the full free spins list or jump to 50 free spins.
