Play Buttons sit inside the core Fan per Step progression loop. Moving earns Fame, Fame raises levels, and better level progression reaches Fan milestones sooner. The official description states that equipping Play Buttons increases Fame earned per step, so the practical comparison is the boost value the game shows—not color, price, or rarity language by itself.
Recent gameplay evidence showed names including Pink, Black, Gold, Plasma, Void, Blue, Green and Yellow Play Buttons. Transcript wording also suggested Heavenly Light and Divine Heaven variants, but those two names have lower confidence because automatic transcripts can distort on-screen labels. We preserve them as reported names rather than presenting them as an official ordered tier list.
The World 3 event announcement explicitly promises new Play Buttons alongside a new world, skins, balance changes and improvements. That makes any permanent 'best button' answer especially fragile. Check the live inventory stat after the update, compare the displayed Fame-per-step effect, and revisit this guide after the event data is verified.
