I looked up
this thread since I liked it when it was first posted for some of the simple ideas for prizes brownfox posted. it's old though
But the games in general that I like and notice being played are...
Dry Erase Board: clearing the board, tipping the secret number (which can also be done without dry erase board), hangman, tic tac toe, pictionary? lol very easy to customize and try new games as well.
Spin wheel: pretty straight forward, price to spin and prizes or lack of prizes on the slots.
Raffles: not sure if that qualifies as a game. but it's like a game of chance and you can do mini raffles for like your cam shift? idk
Cards: I play 21 and Red Black High Low as card games
Balloons: popping balloon game where you put prizes in the balloons and the custies can tip certain amounts to pop a balloon, or maybe have levels with better prize opportunities for different colored balloons that are priced higher to pop.
And it goes on and on, I saw a model play connect 4 before, and darts, and whatever. It's so open to interpretation.
And having something new and different can make a big difference in my opinion as long as it's not too complicated.
I generally think of like carnivals and stuff and find inspiriation off things like that but I know that's not everyone's jam hahaha.
