In this event, there is </span><em><span>no bounty for the function caller</span></em><span>.</span></p><p><span>If one side had no </span><code>$ETH</code><span> in it, but the other did, a new </span><code>round</code><span> is started without taking a </span><code>house_cut</code><span>, so that the </span><code>accounts</code><span> from the previous </span><code>round</code><span> get their refund.

<span>Otherwise, a </span><code>house_cut</code><span> is taken out of the total in the </span><code>round</code><span>, and a bounty is taken from the </span><code>house_cut</code><span>.
