Test the flow on a public screen
Keep personal balance or account details from leaking into a broadcast, avoid prompts during active performance, and make the return to play immediate. Consider overlays, chat attention, spectators, clipping, and how sponsored or purchased visuals will be understood by viewers.
Run a price-comprehension check
Give a new player the offer without explanation and ask them to name the selected item, full Koin amount, available balance, expected balance afterward, quantity or duration, and ownership rule. Let them decline, then repeat with insufficient Koin and a successful choice. Review every place the value appears and remove crossed-out amounts, vague premium labels, unsupported real-currency comparisons, or urgency that distracts from the final cost. The wording on the preview, confirmation, success message, and owned view must describe the same thing. Reopen the game and verify that the balance and ownership shown to the player still match the one transaction they approved.
Keep price and balance together
Place the exact Koin amount beside the current Koin balance and show the expected remaining balance before choosing confirm. For streamers and live audiences, the experience must avoid purchase prompts that interrupt play or expose private account information.
Explain duration and ownership
State whether the item is permanent, consumed on use, limited by quantity, or active for a fixed time. For streamers and live audiences, the experience must avoid purchase prompts that interrupt play or expose private account information.
Remove misleading price signals
Avoid fake urgency, crossed-out prices, unsupported currency comparisons, and labels that hide the final Koin amount. For streamers and live audiences, the experience must avoid purchase prompts that interrupt play or expose private account information.
