A cooktop appliance comprising:

• a gas burner including at least a first burner region and a second burner region;
• an ignitor disposed proximate the gas burner and configured to ignite one of the first and second burner regions;
• and
• a burner drive configured to generate relative rotation between the first and second burner regions of the gas burner to transfer a flame between the first and second burner regions during the relative rotation;
• wherein the gas burner includes a first ring, a second ring, and a cross-over channel configured to communicate a flame between the first ring and the second ring, wherein the first burner region is disposed on the first ring and the second region is disposed on the second ring, wherein the first burner region includes a plurality of flame ports, and wherein the burner drive is configured to generate relative rotation between the first and second burner regions of the gas burner such that the cross-over channel sweeps past the plurality of flame ports during the relative rotation to transfer the flame between at least one of the plurality of flame ports and the cross-over channel during the relative rotation.
