NEVER and EVER spend trying to get main reward from rng events ... most of the times those rng "wheel" events are rigged to 0% chance to get main reward ... so no matter how much You spend there You have ZERO chance to get it. if You are f2p, low spender just stack to 35-60/80k cupons. wait for good fuku event with stars, great tree or great plates same week. best value of Your cupons.
