I hate this idea.
I don’t think that allowances, deserts, computer time or whatever should be portrayed as payment for services. They’re things which kids should get because they’re a contributing member of the household.
The big problem is that if these things are payment, then if they get an outside job or decide that they don’t need allowance (or game time) this week then they just stop contributing. As “eggy toast” implied, once you make a game of the system then the kids will try to game the system. Which is definitely not what you want.
