Product manager focus
Keep the catalog small and the player promise precise. Use the prototype to decide whether the idea deserves engineering effort, not to forecast revenue.

Use a browser-based playable build to work through purchase confirmation for classroom game labs. The goal is to make the player journey concrete before the team commits to native commerce implementation.
Create this game flow
Keep the catalog small and the player promise precise. Use the prototype to decide whether the idea deserves engineering effort, not to forecast revenue.
Design for the input, layout, interruption, and return behavior players expect from classroom game labs.
Use simulated Koin values and instructor review; do not collect student payment data.
Show one item that remains optional, its preview, clearly stated Koin cost, available Koin balance, and ownership rule in a layout suited to classroom game labs.
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.
Define the player need, item scope, ownership rule, Koin price, and free path. Check age context, accessibility, rights, and platform expectations. Use the prototype to resolve player-facing questions before creating platform integration tasks.
For a game product manager, this purchase confirmation prototype should make every player action and result shown in the game easy to evaluate. Write how to show the exact item, Koin amount, balance impact, and explicit confirm/cancel actions. Define the player need, item scope, ownership rule, Koin price, and free path. Check age context, accessibility, rights, and platform expectations. Treat Koin as a classroom game variable and do not request payment details, account credentials, or personal student information. The exercise is about interface states and responsible design.
Ask students to explain the item promise, free path, cancel behavior, failure recovery, and production boundary. Grade reasoning and playtest evidence rather than purchase completion.
Run the prototype on shared devices with accessible controls and privacy-safe displays. Native billing, identity, durable storage, refunds, platform approval, and real transactions remain outside the lab.
State which player problem the item addresses, why a purchase is appropriate, and what evidence would cause the team to drop the idea. The prototype supports a product decision; it does not forecast revenue.
Ask testers to complete the same goal with and without the item. Look for comprehension, pressure, fairness, and delivered value rather than using purchase completion as the only measure of a good experience.
Review age context, accessibility, localization, rights, moderation, platform policy, refunds, support, and security with the responsible owners. Keep unverified native capabilities and financial reporting out of the public promise.
The confirmation should repeat the selected item, exact Koin amount, balance before spending, remaining balance, and ownership rule without introducing a different offer. Test that behavior using classroom game labs. Use simulated Koin values and instructor review; do not collect student payment data.
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 classroom game labs. Use simulated Koin values and instructor review; do not collect student payment data.
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 classroom game labs. Use simulated Koin values and instructor review; do not collect student payment data.
Choose the input and screen behavior for classroom game labs. 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
Define the player need, item scope, ownership rule, Koin price, and free path. Check age context, accessibility, rights, and platform expectations.
Result: Product manager focus
Ask players what they expect before confirming and what they received afterward. Remove pressure language and unsupported platform claims. Repeat the test after interruption and reload.
Result: A stable prototype
Create a non-production demonstration of purchase states for a game product manager. 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 product manager must be able to balance player clarity, catalog scope, and release risk. Do not add subscriptions, payment-provider UI, revenue analytics, or native platform claims. State this boundary: Use simulated Koin values and instructor review; do not collect student payment data.
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. Use simulated Koin values and instructor review; do not collect student payment data.
Open the complete prompt in SEELE, adjust the item and Koin price, then generate a playable version you can test.
