Earned resources
Name every resource produced by play, the activities that create it, the storage limits, and the decisions it supports.
Direct Answer
Design the whole economy around player choices
A useful economy model connects resource flow, progression, the sellable catalog, Koin pricing, fairness, and creator earnings in one reviewable plan.
SEELE IAP lets creators sell items or content in AI-generated games. Players buy with Koin, and eligible purchases create creator earnings. This designer helps you decide what belongs in that loop and how it stays balanced.
Economy Layers
Separate earned resources, progression, and Koin offers
Each layer needs a distinct job so players can understand how play and optional purchases relate.
Progression
Define milestones, upgrade costs, unlock timing, and the expected path through early, middle, and later sessions.
Sellable catalog
List optional items or content, the player value of each offer, its Koin price, and the result delivered after purchase.
Sources And Sinks
Balance what enters the economy with what leaves it
Sources create resources; sinks remove them in exchange for progress, expression, or new choices.
Build a table with the source or sink name, frequency, amount range, player action, and progression effect. Test a new player, a steady player, and a highly engaged player. Look for idle stockpiles, impossible costs, one dominant activity, or rewards that stop mattering. Revise one assumption at a time so the effect remains traceable.
For idle games, include active gains, offline gains, upgrades, reset layers, and milestone timing. For session games, compare reward cadence with the time between meaningful choices. A fair system can be generous without making every resource meaningless.
Koin Pricing
Price sellable items from utility, visibility, and duration
The Koin amount should make sense beside the offer's role in the game.
Record the item or content name, preview, quantity, duration, progression effect, and free alternative before choosing a price. A persistent cosmetic, a one-use consumable, and an optional content area create different kinds of player value. Keep each offer legible and avoid several products that solve the same need.
Use the SEELE IAP item and content guide to shape the storefront and purchase flow. Use the Monetization Design Tool to organize the wider catalog and creator-sales plan.
Fairness And Earnings
Protect the free baseline while supporting the creator
A strong economy gives optional purchases a real value without turning ordinary play into a problem.
Write down what remains playable without buying. Show the item, contents, duration, and exact Koin amount before confirmation. Check that progression pressure does not make the offer feel mandatory. When a player completes an eligible Koin purchase, the purchase contributes to creator earnings under current SEELE product terms.
Before release, review the numbers, game feel, catalog wording, item delivery, age suitability, rights, and player choice. Generated values are starting hypotheses; representative play paths decide whether the economy is ready.
