Yes, there can be. Some free spins offers may be restricted to certain games, and if those are not the games you like to play then they won’t be of any use to you. There could also be restrictions on the allocation of free spins e.g. 50 free spins that are allocated 10 free spins per day for five days. You may also find that some free spins are only available for a certain period of time, so make sure you use them before they expire.
