i put a mixture of super fun assignments and less-desirable tasks together...
and stuck them in a bowl.
it would have worked awesome except that Liam pulled out "give mom a hug and a kiss" first and Finn drew "do a silly dance" first. Ossi, on the other hand drew, "gather all the toys from downstairs and take them upstairs" which is his absolute least favorite chore in the whole wide world.
so from that moment on this game was "really stupid."
Ossi eventually came around when i pulled out a bunch of papers at once and let him choose one half to do and one half to put back.
maybe this idea will work for you. :)
