I fixed it! super easy! I have a firestrike and a sharpfire I think 3 darts is not enough so I grabbed some from my sharpfire. they worked for a while but then it stopped working. I was all sad be couse I thought it broke, when I looked closer at the darts I noticed 3 of them had a W and the others had a Y! aperently the elite darts have more groups! the w's are for the firestrike! I hope it helped, sorry if this didnt help. have a good day!
