Prize Configuration

Lucky-draw games (Spin the Wheel, Gachapon, Grid Box, Scratch Card, Card Pull, and Claw Machine) use a prize configuration system. This guide explains how to set up, manage, and monitor prizes.

Prize Types

Each prize slot must be one of six types:

Type	What the player gets	Fulfillment
Voucher Set	A unique code pulled from a managed set	Automatic (tracked)
Voucher	A fixed code string (e.g., “SAVE20”)	Shown directly to player
Item	A named physical/digital prize	Manual (you fulfill)
External Link	A URL where the player redeems separately	Player follows link
Custom Voucher	A code issued by an external provider	Automatic via webhook (your system)
No Prize	”Try again” — no reward given	N/A

When to use each type

• Voucher Set — Best for campaigns with many unique codes (one per winner). Codes are auto-assigned from your inventory and tracked.
• Voucher — Use for a single shared code that all winners see (e.g., a universal discount code).
• Item — Physical merchandise, free products, or service upgrades that require manual fulfillment.
• External Link — Drive traffic to a landing page, partner offer, or redemption portal.
• Custom Voucher — Best when your codes live in another platform (e.g., an e-commerce store or loyalty system). DailyPlay requests a code from your provider at claim time via a webhook, so inventory stays in your own system.
• No Prize — Essential for balancing probabilities. Without “try again” slots, every play results in a win.

---

Custom Voucher (Webhook-Connected)

The Custom Voucher type delegates fulfillment to an external provider. Instead of pulling a code from a DailyPlay voucher set, the player’s claim triggers a webhook to your provider, which returns the real code. Use this when your codes are managed outside DailyPlay.

Prerequisite

A Custom Voucher prize is only available once an organization admin has set up a voucher webhook connection. If no connection exists, the option won’t appear in the prize editor. See Connections to set one up.

Provider vs. Connection

There are two layers behind this prize type:

Layer	What it is
Provider	A template that defines what fields the provider needs and how its webhook is shaped (e.g., a store integration).
Connection	Your organization’s live, credentialed instance of a provider — the actual webhook URL and credentials.

A provider is the definition; a connection is your configured hookup to it. An organization can have more than one connection to the same provider (for example, separate “Staging” and “Production” stores).

Selecting a Connection

In the prize Type selector, each active voucher webhook connection appears as its own button alongside the standard types. Selecting one:

• Binds the prize to that connection and its provider
• Auto-fills the prize name with the connection name (if the name is still blank)
• Reveals the Voucher fulfillment panel for provider settings and quantity

If your organization has multiple connections, each is shown as a separate button so you can pick exactly which one fulfills the prize.

Provider Settings (Fields)

Some providers require extra configuration per prize — for example, a discount or cart-rule identifier. These fields render automatically under Provider settings when you select the connection. Each field may be:

• A text, number, or yes/no value
• Marked required (the prize won’t save until it’s filled)
• Constrained by minimum/maximum values, length, or format (e.g., email)

DailyPlay validates these fields both in the editor and again server-side before saving, and re-checks that your organization still has access to the provider.

Quantity and Inventory

Custom Voucher prizes support the same inventory tracking as other limited prizes:

Field	Description
Total	Maximum number of times this prize can be won. Leave empty for unlimited (max 1,000,000).
Remaining	Read-only. Shows remaining / total. For a new prize it mirrors the total; after saving it reflects live wins.

When a Custom Voucher prize reaches 0 remaining, it’s excluded from future draws, and probability redistributes among the remaining eligible prizes — exactly like other prize types.

How Fulfillment Works

1. The player wins the Custom Voucher prize and claims it
2. DailyPlay sends a webhook to the connected provider, including the prize’s provider settings and player context
3. The provider responds with the actual voucher code
4. The code is returned to the player

Setting Up Prizes

In the Game Editor

When creating or editing a lucky-draw game, you reach the Prizes step in the editor. Each prize is a “slot” you add and configure. The core flow for a single slot is:

1. Click Add Prize Slot — a new slot card appears
2. Enter a Name — the display name players see (e.g., “10% Off”)
3. Choose a Type — pick one of the prize types (Voucher Set, Voucher, Item, External Link, Custom Voucher, or No Prize)
4. Set the Win Chance (%) — the slot’s probability in the draw
5. Repeat for each prize, then make sure all chances total 100%

Type-specific fields (voucher set, external URL, provider settings, etc.) appear automatically once you pick the matching type.

Example: How to set up an item prize in the game:

Prize Slot Fields

Field	Description	Required
Name	Display name shown to the player (max 50 chars)	Yes
Description	Additional details (max 200 chars)	No
Type	One of the 6 prize types above	Yes
Win Chance (%)	Probability of winning this slot (1–100%)	Yes
Quantity	Total available (leave empty for unlimited)	No
Min Score	Minimum score required to be eligible	No
Voucher Set	Which set to pull codes from (voucher set type only)	Conditional
External URL	Redemption link (external link type only)	Conditional
Image	Custom prize image (max 10 MB, resized to 256×256)	No

Display Order

The order you arrange prizes in the editor directly controls how they appear in the game (e.g., wheel segments, grid cells). Use the Move Up/Down buttons to arrange them. Display order does not affect win probability — only the chance percentage matters for odds.

Probability Rules

All prize chances across a game must total 100% or less.

Validation Rules

• Each slot must have a chance greater than 0%
• The sum of all slots cannot exceed 100%
• DailyPlay validates both in the editor and server-side before saving

When the total isn’t valid, the editor shows an inline warning and blocks you from continuing until it’s fixed.

Example: Spin the Wheel (8 slots)

Slot	Prize	Type	Chance	Quantity
1	$50 Gift Card	Voucher Set	5%	10
2	20% Off	Voucher Set	10%	50
3	10% Off	Voucher	15%	Unlimited
4	Try Again	No Prize	20%	Unlimited
5	Free Shipping	Voucher	10%	Unlimited
6	Try Again	No Prize	15%	Unlimited
7	Visit Our Blog	External Link	15%	Unlimited
8	Try Again	No Prize	10%	Unlimited
—	Total		100%

Example: Gachapon (6 capsules)

Capsule	Prize	Type	Chance	Quantity
Gold	$50 Voucher	Voucher Set	2%	10
Silver	$20 Voucher	Voucher Set	8%	50
Bronze	$10 Voucher	Voucher Set	20%	100
Blue	10% Off	Voucher	30%	Unlimited
Green	5% Off	Voucher	25%	Unlimited
Gray	Try Again	No Prize	15%	Unlimited

Invalid Configuration

If chances exceed 100%, DailyPlay will block saving. If they total less than 100%, the remaining percentage becomes an implicit “no win” outcome during the draw.

Minimum Score Requirements

For games that combine skill with luck, you can set a minimum score per prize slot. Players must achieve at least that score before the prize becomes eligible in the draw.

How it works:

1. Player finishes the game with a score
2. Server filters prizes — only those where min_score ≤ player's score are included
3. Weighted random draw occurs among eligible prizes only

Example:

Prize	Chance	Min Score
Grand Prize	5%	1000
Runner Up	15%	500
Consolation	30%	0
Try Again	50%	0

A player scoring 750 is eligible for Runner Up, Consolation, and Try Again — but not Grand Prize.

Score gates

Use min score to reward skilled players with access to better prize tiers while still giving everyone a chance at smaller prizes.

Highest Tier Only

For games that support minimum scores, a Highest Tier Only toggle appears at the top of the prize editor. When enabled, a player draws only from the highest score tier they qualify for, instead of from every eligible tier combined.

• Off (default): All prizes with min_score ≤ player's score are pooled together for the draw.
• On: Only the prizes in the single highest tier the player unlocked are eligible — lower tiers are excluded.

Use this when you want top performers to compete only for the best rewards, rather than diluting their odds with consolation prizes.

Quantity and Inventory

Limited Quantity

Set a total quantity for high-value prizes:

• The remaining_quantity decrements each time the prize is won
• When it reaches 0, the prize is excluded from future draws
• Remaining prizes’ probabilities auto-adjust proportionally

Unlimited Prizes

Leave quantity empty for prizes you can always fulfill:

• Digital codes, voucher sets with large inventories, external links
• No inventory tracking needed

What Happens When Depleted

1. The depleted prize is skipped during the draw
2. The system redistributes probability among remaining eligible prizes
3. If all prizes are depleted, the game returns no prize

---

Active / Inactive Prizes

Each prize has an is_active flag:

• Active — Included in draws, shown with a green badge in the dashboard
• Inactive — Excluded from draws, shown with a gray badge

Use this to temporarily disable a prize without deleting it (e.g., pause a promotion, swap prizes mid-campaign).

---

How the Draw Works

DailyPlay uses a server-side cryptographic draw — prize selection cannot be manipulated from the frontend:

1. Game calls the draw endpoint with the game ID
2. Server fetches all active, eligible prizes (with inventory and score checks)
3. Weighted random selection picks a winner based on chance percentages
4. A signed token (HMAC-SHA256) is generated containing the result
5. Token is valid for 30 minutes
6. When the player claims, the server verifies the token signature before awarding

Claim Processing by Type

Prize Type	What happens on claim
Voucher Set	Next available code assigned, voucher marked claimed
Voucher	Fixed code string returned to player
Item	Prize name displayed, player fills claim form
External Link	URL returned, player redirected to external redemption
Custom Voucher	Webhook sent to your provider, returned code shown to player
No Prize	”Try again” message shown

Connection Events

Every prize claim triggers outbound integrations if configured:

• Zapier, Braze, Mailchimp, HubSpot, Salesforce, Segment, or custom webhooks
• Event payload includes: game ID, player UUID, score, prize name, prize type, voucher code

Best Practices

Probability Balance

Recommended distribution for player engagement:

Tier	Chance Range	Purpose
High-value	2–10%	Creates excitement and aspiration
Medium	15–30%	Keeps players feeling rewarded
Low-value	25–40%	Frequent small wins
No prize	20–40%	Creates anticipation for retry

Win rate

Aim for a 50–70% overall win rate (some prize, even small). If “no prize” dominates, players disengage quickly.

Visual Appeal

• Upload custom images for each prize — players see them in the game UI
• High-value prizes with compelling images drive more engagement
• Images are resized to 256×256px automatically

Testing Before Launch

1. Play the game multiple times in preview mode
2. Verify all prize types display correctly (codes, links, names)
3. Check that voucher set prizes actually deliver a code
4. Confirm quantities decrement properly
5. Test with scores below and above min_score thresholds (if used)

---

Troubleshooting

Player won but no code displayed

1. Check that the linked voucher set still has available codes
2. Verify the set hasn’t expired
3. The prize may have hit its quantity limit — check remaining inventory

Probabilities seem wrong

• Verify totals equal 100% in the editor
• Small sample sizes will naturally appear skewed — test with 50+ plays
• If some prizes are depleted, remaining prizes effectively have higher chances

Prize not showing in game

1. Confirm the prize is active (not inactive/disabled)
2. Check that remaining_quantity isn’t 0
3. Ensure the game is published (not in draft mode)
4. If using min_score, verify the player’s score meets the threshold

”Token expired” on claim

The draw token is valid for 30 minutes. If a player waits too long between seeing the result and claiming, the token expires. This is rare in normal gameplay.
