How a Student Team Can Add a Koin Convenience Upgrade to a Farming Game
Build the farming game first, then add one optional convenience upgrade that supports the existing play loop. This guide keeps the item understandable from its first preview through delivery and reload.
Create this game flow
Plan the convenience upgrade around the game
Why it fits farming
A farming browser prototype centered on seasonal routines, crop goals, and homestead expression.
What the item offers
A convenience upgrade preview with a concrete description and direct Koin price.
A practical farming example
Offer moment
Place the convenience upgrade after this loop advances: a farming browser prototype centered on seasonal routines, crop goals, and homestead expression. Wait for a safe pause. Player progress must not depend on the offer.
Offer card
Offer-card rules: Connect value to the season; Show the before-and-after limit. Show the item, benefit, ownership or duration, balance, and full price in Koin. Keep confirm and cancel separate.
Successful result
Test preview, confirm, insufficient balance, success, apply the durable convenience entitlement and show the changed limit, and reload. Show that change inside normal play instead of relying only on a success message.
Free path
Test a free session around a farming browser prototype centered on seasonal routines, crop goals, and homestead expression. If play becomes incomplete, fix the game before changing the offer.
Design the convenience upgrade in detail
Choose a quiet farm moment
Use the farmhouse, storage screen, market close, or start of a day after crops and animals are safe. Avoid offers while watering, harvesting, or racing an in-game clock.
Connect value to the season
Explain whether the item is decorative, adds storage, opens a side area, or supplies a fixed quantity. Do not imply that a seasonal crop or festival reward requires the purchase unless it truly does.
Inspect the homestead after reload
Confirm that fields, planted crops, tools, animal care, and the calendar remain stable. The delivered item should appear in the correct chest, wardrobe, building menu, or map location.
Carry the item across a full farm day
This farming game uses a farming browser prototype centered on seasonal routines, crop goals, and homestead expression. Review the genre through choose a quiet farm moment and connect value to the season. For a student team, the convenience upgrade should support that loop without becoming mandatory. Review the item through show the before-and-after limit and treat the upgrade as durable. A student team can split the demonstration between the game loop, interface explanation, and classroom playtesting. The example offer is: A convenience upgrade preview with a concrete description and direct Koin price. This offer emphasizes less friction while preserving the playable free path before expanding the catalog. Begin at the farmhouse with a recorded date, weather, crop stages, tool levels, animal care, storage, and festival progress. Open the choice only after urgent chores are safe. Cancel and continue the day without losing time or selected tools, then try insufficient Koin from the same menu. Buy the item, locate it in the chest, wardrobe, building menu, or map, and use it only as described. Sleep to the next day and reopen the game. Check that planted crops advanced normally, animals retained care state, seasonal goals remained available, and the Koin item neither duplicated nor replaced an earned reward. Ordinary farm routines must still feel complete without it.
Frame it as a design exercise
Use Koin as simulated game value and explain that the project demonstrates interface states and player choice. Do not collect card details, account credentials, personal information, or money for a classroom prototype.
Divide the demonstration clearly
One teammate can build the game loop, another can own interface wording, and another can run the playtest. Everyone should be able to explain why the item is optional and where it appears after confirmation.
Document what the prototype omits
List native billing, identity, durable storage, security, refunds, age rules, accessibility, and platform review as future production concerns. This shows technical understanding without pretending the browser project solves them.
Present both success and failure
During the demo, cancel once, attempt the item without enough Koin, complete a valid choice, and reopen the game. Explain which results are simulated and what would require real engineering in a released product.
Explain the system during a live demonstration
Prepare a short presentation that begins with the playable core activity, then shows a voluntary item preview, decline, insufficient Koin, valid confirmation, delivery, and reopening. Each teammate should explain one design reason and one technical boundary rather than reading the interface aloud. Include a diagram or note showing which values are simulated and which production systems are absent. Ask classmates to identify any pressure language, inaccessible control, unclear ownership rule, or privacy concern. Finish by describing how identity, durable storage, security, refunds, native policy, and testing would change a real implementation, without collecting personal or payment information during the exercise.
Prove the improvement without manufacturing discomfort
Display the current capacity, preset count, queue size, travel option, or workflow limit beside the precise improvement and show whether ownership is permanent. Play a representative session without it and record whether storage, repetition, waiting, or navigation already feels intentionally designed. If the free experience is cramped or slow only to sell relief, repair that baseline first. Complete the choice, apply the new limit in its normal screen, fill or use the added capacity, and reopen the game. The higher limit should remain visible and should never appear buyable again for the same account state. Check that a cancelled choice preserves existing configuration, insufficient Koin changes nothing, and the upgrade helps without turning ordinary progression into a penalty.
Show the before-and-after limit
Display the current capacity or workflow and the exact improvement, such as additional inventory slots or another saved preset.
Treat the upgrade as durable
Once buying is complete, apply the new limit visibly and preserve it after reload. Do not make the player buy the same permanent improvement again.
Remove artificial friction
Test the game without the upgrade. If normal play feels deliberately slow, cramped, or repetitive only to sell relief, improve the free experience first.
Build it in five steps
1. Finish the farming loop
Make the main activity playable before adding the convenience upgrade. Players need context to judge whether the item is useful.
Result: A working farming foundation
2. Write one item definition
A convenience upgrade preview with a concrete description and direct Koin price. Keep the same wording in the preview, confirmation, and delivered state.
Result: A consistent player promise
3. Generate the purchase choice
Show the exact Koin amount, current Koin balance, confirm, cancel, and what ownership means. Divide the work between the game loop, interface copy, and playtesting. Explain why the item is optional and how the game stays complete without it.
Result: An understandable decision
4. Deliver and recover
Test preview, confirm, insufficient balance, success, apply the durable convenience entitlement and show the changed limit, and reload. Then test not enough Koin, cancellation, repeated input, interruption, and reload.
Result: A visible, stable result
5. Test as a student team
Demonstrate confirm, cancel, too little Koin, success, delivery, and reload. Do not collect payment details, account data, or personal information.
Result: Student team plan

Prompt 1
Create a browser-playable farming game prototype for a student game team. Build the core loop around seasonal routines, crop goals, and homestead expression. Add one optional convenience upgrade offer containing an inventory expansion with before-and-after capacity, Koin price, and persistent owned state. Price it directly in Koin, require an explicit confirmation, show the balance effect, and apply the durable convenience entitlement and show the changed limit. Do not add subscriptions, external payment checkout, revenue reporting, or guaranteed earnings. Include insufficient-Koin, cancel, success, and reload states.
Prompt 2
Keep the item optional. Show its precise Koin price, balance before spending, confirm, cancel, low-balance, success, visible delivery, and reload states.
Student Team playtest checklist
- The convenience upgrade supports the existing farming loop.
- The item benefit and ownership rule are clear ahead of confirmation.
- The full price in Koin and current Koin balance appear together.
- A cancelled choice returns to play without loss or pressure.
- Success visibly delivers the confirmed convenience upgrade.
- Demonstrate confirm, cancel, too little Koin, success, delivery, and reload. Do not collect payment details, account data, or personal information.
Before you publish
- Avoid this design problem: turning ordinary play into artificial friction that exists only to sell relief.
- This guide uses a direct Koin transaction for one optional game item. It does not create a subscription or recurring charge.
- The result is a playable browser prototype. Native billing, identity, durable entitlements, security, refunds, and store approval need separate implementation.
- SEELE does not provide payment analytics, tax tools, payout reports, or guaranteed revenue through this flow.
Frequently asked questions
What should this farming offer contain?
A convenience upgrade preview with a concrete description and direct Koin price. Start with one item and one price.
Is this a subscription?
No. The player spends Koin directly on one named item or unlock.
What happens if the player cancels?
Return to the same game state without spending Koin or delivering the item.
What if the Koin balance is too low?
Explain the shortage, preserve progress, and do not deliver the item.
Does this include payment or revenue reports?
No. It covers the player-facing purchase experience, not financial reporting.
Is the prototype ready for a native store?
No. The browser prototype still needs native billing, persistence, security, refunds, and platform approval.
