<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">betting machine</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tote that I've seen before include "system that could be for the better" , "Carry; betting device" , "Form of betting: carry" , "System of betting on horse races" , "Transfer" .)
