Game designer focus
Start with player motivation and the core loop. The item should support a goal players already understand rather than remove deliberately created frustration.

Use a playable web prototype to work through purchase recovery for desktop web 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 desktop web games.
Desktop browser purchases remain Koin flows inside the supported experience.
Show one non-required item, its preview, specific Koin amount, current Koin balance, and ownership rule in a layout suited to desktop web games.
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Keep each change visible to the player rather than hiding it in technical state.
Make cancellation, not enough Koin, 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 recovery prototype should make every player action and player-visible outcome easy to evaluate. Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Choose the offer moment, explain the game benefit, and protect the complete free path. Compare the experience before and after ownership. Check tab order, focus indicators, mouse targets, escape behavior, and the return to game controls. Confirmation must never borrow an input that also performs a high-frequency gameplay action.
Keep the item, Koin amount, balance effect, and actions together on common desktop widths. Avoid pushing a player cancellation off screen simply because the game canvas occupies a large area.
Resize, move between displays, zoom, refresh, and restore a background tab. The interaction should preserve the selected item and resolve pending or delivered states without another grant.
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.
If delivery is interrupted, explain whether the result is pending, safe to retry, or already complete. Do not show both failure and success. Test that behavior using desktop web games. Desktop browser purchases remain Koin flows inside the supported experience.
Repeated clicks and reloads should resolve to one purchase result. The player must never receive duplicate items or lose Koin twice. Test that behavior using desktop web games. Desktop browser purchases remain Koin flows inside the supported experience.
A player cancellation, too little Koin, and recoverable errors should preserve progress and offer a clear return or retry action. Test that behavior using desktop web games. Desktop browser purchases remain Koin flows inside the supported experience.
Choose the input and screen behavior for desktop web games. State the platform limit beside the prototype brief.
Result: An honest scope
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. Describe the player action and visible response at each point.
Result: A clear purchase recovery 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 keyboard-and-mouse browser play for a game designer. Focus the IAP prototype on handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. 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: Desktop browser purchases remain Koin flows inside the supported experience.
Keep the item optional. Show its specific Koin amount, current Koin balance, confirm, cancel, low-balance, success, visible delivery, and reload states.
Write how to handle reloads, interrupted delivery, duplicate clicks, and insufficient Koin without double granting. 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. Desktop browser purchases remain Koin flows inside the supported experience.
