>The cost per spin is the thing that makes it gambling.
The "landlord" aka casino is constantly requiring that you pay `X credits within N spins` or else it's game over. That is just moving when the subtraction of player's credits happens from every spin to every few spins. It's effectively X/N credits per spin, per "rent" notice. That's a core game mechanic.
You realize you're trying to argue that this is appropriate for children, where the whole game is they pretend to be a gambling addict trying to make their ever-increasing rent payments (which children don't have) by taking spins at a video slot machine.
