Game Designer guide · PWA Games · Koin purchase UX
Use a playable browser prototype to work through purchase confirmation for PWA games. The goal is to make the player journey concrete before the team commits to native commerce implementation.
Create this game flow
Start with player motivation and the core loop. The item should support a goal players already understand rather than remove deliberately created frustration.
Design for the input, layout, interruption, and return behavior players expect from PWA games.
PWA packaging does not create native platform IAP entitlements.
Show one item the player may decline, its preview, precise Koin price, balance before spending, and ownership rule in a layout suited to PWA games.
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Keep each change visible to the player rather than hiding it in technical state.
Make a cancelled choice, a Koin shortage, pending, interrupted delivery, and reload visually distinct, with a safe next action.
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Use the prototype to resolve player-facing questions before creating platform integration tasks.
For a game designer, this purchase confirmation prototype should make every player action and clearly displayed outcome easy to evaluate. Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Try the flow in a regular tab and an installed presentation. Navigation, focus, and recovery should remain understandable even when browser controls are reduced or the app resumes from suspension.
An unavailable connection must not look like a completed purchase. Explain when the action cannot continue, preserve the game state, and provide a safe retry after connectivity returns.
PWA installation does not create platform IAP ownership. Durable identity, cross-device state, refunds, billing integration, and app-store policy remain outside the browser prototype.
Run the game without opening the purchase choice, then run it with the item. Compare pacing, motivation, difficulty, and recovery so the offer supports play instead of repairing frustration that was added deliberately.
Describe what changes on screen, how long it lasts, where it appears, and what remains available without it. Replace value labels such as better or premium with rules a player can observe.
Check what the player was doing immediately before the offer and where cancel returns them. The item should arrive after enough context to understand it, but never during a time-critical or emotionally pressured action.
The confirmation should repeat the selected item, exact Koin amount, current Koin balance, remaining balance, and ownership rule without introducing a different offer. Test that behavior using PWA games. PWA packaging does not create native platform IAP entitlements.
Use distinct actions with clear labels and enough spacing for the target input method. Returning to the game should never spend Koin. Test that behavior using PWA games. PWA packaging does not create native platform IAP entitlements.
After confirmation, show a pending state and disable repeated input until the result is known. A slow response should not create duplicate grants. Test that behavior using PWA games. PWA packaging does not create native platform IAP entitlements.
Choose the input and screen behavior for PWA games. State the platform limit beside the prototype brief.
Result: An honest scope
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Describe the player action and visible response at each point.
Result: A clear purchase confirmation sequence
Show the item, exact price, balance, confirm, cancel, pending, success, and delivery without payment-provider screens.
Result: A complete player journey
Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership.
Result: Game designer focus
Play cancellation and a full session without purchase. Check timing, value, competitive impact, and whether the item matches the delivered result. Repeat the test after interruption and reload.
Result: A stable prototype
Create installable web presentation and offline-aware states for a game designer. Focus the IAP prototype on show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Use a direct Koin item transaction with preview, exact price, confirmation, cancel, insufficient balance, success, delivery, and reload behavior. The game designer must be able to connect the offer to the core loop and player motivation. Do not add subscriptions, payment-provider UI, revenue analytics, or native platform claims. State this boundary: PWA packaging does not create native platform IAP entitlements.
Keep the item optional. Show its clearly stated Koin cost, available Koin balance, confirm, cancel, low-balance, success, visible delivery, and reload states.
Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. The result is shown as a playable Koin flow.
No. The player spends Koin directly on one named item or unlock.
Return to the same game state without spending Koin or delivering the item.
Explain the shortage, preserve progress, and do not deliver the item.
No. It covers the player-facing purchase experience, not financial reporting.
No. PWA packaging does not create native platform IAP entitlements.
