If you are playing in the Attack or Revenge mode, and your ritual is started and not paused, you will receive a bonus to the ritual during the respin.
 
If the ritual is cancelled, the bonus is lost.
 
The reward depends on the sector where the arrow stops: green (the gem), purple (the bonus).
 
A regular spinner (without the bonus to the ritual) will appear if:
 
  • You are playing in Attack or Revenge mode, but the ritual is not running;
  • You are retrieving your own or someone else's gem.
 
Note: the respin bonus will not increase your gem's rating beyond the maximum limit (999 999). You will still need to fuse gems through the ritual to get a rating of 1 000 000 or higher.
