a flash game exists but it's shit
pinball but you build the board; you're given some free points and 3 free balls. spend points on table elements like flippers and bumpers. play the table to earn points and when your balls are spent you have to spend points to get your next 3 balls, while remaining points can be spent on more table objects and stuff
after the cost of 3 more balls exceeds your point total, all earned points are tallied for your highscore. plinko mode with no flippers, maybe, too
