I've been having an issue with tame a horse. I know you use sugar cubes to inrease your chance, but I can't seem to find the ability to do so. I don't know if this is a bug, or if I'm just blind or can't see. Anyone here can help me out? Maybe a screenshot of the button to use the sugar cube or directions. The Tutorial wasn't that clear and I never really neede to cube that I was given for it. Much appreciate the help.

You need to sneak near the horse first and use the rope icon. then you need to get close slowly wen you get enough close to the horse the sugar icon will be show up 

 

Start the process far away. Don’t just walk up to the thing and try to rope it

I had this same problem and I had to watch a few YouTube videos until I noticed what I was doing wrong. When you first lasso the horse, make sure you are not close to it. It always rises up and kicks at first and if you are too close it'll just cancel the whole thing and the horse runs away. Stand back like 5-10 meters from it, press the lasso button, then move close to the horse AFTER it does its first kick. You'll be able to feed it sugar and then attempt to catch easily after that.

 

After you throw the lasso at the horse and walk up to it you’ll have two option one to start the mini game the other to feed it sugar

Thank you all for the help! I managed to get ont he horse finally. xD
