Boba Sort: Official Reward Odds & Drop Rate Disclosures

Last Updated: August 2026
App Version: 1.0+

At Boba Sort, we are committed to complete transparency, fair play, and compliance with global digital marketplace disclosure standards (including Apple App Store Guideline 3.1.1). This document provides detailed information regarding the drop rates, base probabilities, dynamic balancing systems, and reward mechanics across all randomized and deterministic features in the game.

1. Standard Disclosure Hierarchy

Rewards in Boba Sort are categorized into Randomized Reward Boxes (where drop rates apply) and Fixed Milestone Tracks (where rewards are 100% deterministic upon achievement).

2. Daily & Monthly Challenge Reward Boxes (Mystery Boxes)

Daily Mystery Boxes and Monthly Challenge Milestone Boxes present players with 6 face-down cards. When opened, players pick 1 card from the pool.

Baseline Category Drop Rates

Before dynamic adjustments or performance tuning are applied, the 6 cards in a box represent the following base distribution:

Category | Base Card Count | Base Category Probability

Coins | 4 out of 6 cards | 66.67%

Infinite Lives | 1 out of 6 cards | 16.67%

Cafe Aesthetic Star | 1 out of 6 cards | 16.67%

Specific Item Odds & Sub-Rarities (Baseline)

Within each category pool, individual item quantities and sub-rarity drop rates across the 6 cards are allocated as follows:

Note: Coin values (100, 300, 900) and Infinite Lives duration (10 minutes) are baseline defaults configured via server configuration.

Dynamic & Adaptive Mechanics (Daily Boxes)

A. Progressive Bad-Luck & Over-Reward Protection (Deficit Balancing)

To protect players from long strings of bad luck and prevent reward clumping, Boba Sort tracks cumulative lifetime pulls from Challenge Boxes.

Bad-Luck Pity (Deficit Recovery): If your cumulative pull history for a high-value item (such as Stars, Infinite Lives, or 900 Large Coins) falls 1.0 or more pulls below its statistical baseline average, coin slots in your next box are dynamically replaced with the missing item type.
Anti-Clumping (Excess Protection): If you have pulled an item type 1.0 or more pulls above its expected baseline frequency, that specific item type is temporarily replaced with Medium or Small coin slots in subsequent boxes until statistical equilibrium is restored.

B. Struggling Player Pity System (Adaptive Performance Tuning)

If a player experiences difficulty on their current level and accumulates 4 or more consecutive failures, the system automatically activates a special Pity Pool for their next Challenge Box to assist in level completion:

Struggling Pity Item | Card Count | Adjusted Category Odds

Infinite Lives (10 Mins) | 2 cards | 33.33%

Infinite Lives (30 Mins) | 1 card | 16.67%

Total Infinite Lives Pool | 3 cards | 50.00%

Medium Coins (300 Coins) | 1 card | 16.67%

Large Coins (900 Coins) | 1 card | 16.67%

Total Coins Pool | 2 cards | 33.33%

Cafe Aesthetic Star | 1 card | 16.67%

3. Win Streak Reward Boxes

Win Streak Boxes are awarded every time a player achieves a level win streak that is a multiple of 5 (e.g., 5, 10, 15, 20 consecutive level victories). A Win Streak Box presents 4 face-down cards, and the player chooses 1 card.

Baseline Category Drop Rates

Cafe Aesthetic Stars: 100.00% (All 4 presented cards contain Cafe Stars).
Coins / Infinite Lives: 0.00%.

Specific Item Odds & Sub-Rarities

Each of the 4 cards features 1 Star for an eligible unlocked cafe location, selected independently using the Dynamic Cafe Star Weighting System described in Section 5.

4. Shop Star Boxes (Purchased Star Packs)

Star Packs purchased from the in-game shop award direct Cafe Aesthetic Stars across unlocked cafes.

Baseline Category Drop Rates

Cafe Aesthetic Stars: 100.00% across all pack tiers.

Pack Configurations & Sub-Rarities

Pack Name | Total Picks | Stars Granted Per Pick | Total Stars Awarded | Distribution Logic

1 Star Pack | 1 pick | 1 Star | 1 Star | Single weighted draw from unlocked cafes.

5 Star Pack | 5 picks | 1 Star | 5 Stars | 5 sequential weighted draws. Duplicates stack onto single cards.

50 Star Pack | 10 picks | 5 Stars | 50 Stars | 10 sequential weighted draws of 5 stars each. Duplicates stack onto single cards.

Intra-Pack Dynamic Decay

For multi-pick packs (5 Star and 50 Star packs), each star drawn immediately increases that cafe’s recorded star total during the sampling process of that specific pack. This dynamically reduces the likelihood of drawing the exact same cafe repeatedly in a single purchase.

5. Dynamic Cafe Star Selection Weighting Algorithm

Whenever a Cafe Aesthetic Star is drawn (from a Challenge Box, Win Streak Box, or Shop Star Pack), the specific cafe selected is determined by a dynamic weighted sampling algorithm.

Drop Pool Eligibility

Eligibility Prerequisite: A cafe enters the reward drop pool only when unlocked by level progress or total star achievements. Locked cafes have a 0.00% drop chance until their unlock criteria are satisfied.

Progressive Weighting Formula

To assist players in balancing upgrades across their entire collection, selection weights for unlocked cafes decay as earned stars increase:

Selection Weight=1 / (Stars Earned in Cafe+1)

Effect on Odds: Cafes with fewer accumulated stars have a significantly higher relative drop weight than mature, heavily-upgraded cafes.

Maxed Cafe Threshold Penalty

Threshold Adjustment: When a cafe reaches 100 Stars, its selection weight is automatically halved (
Weight×0.5
Weight×0.5).
Effect on Odds: This drop-off further penalizes maxed cafes, shifting relative drop probabilities toward remaining non-maxed cafes.

6. Deterministic & Non-Random Rewards

The following features in Boba Sort do not utilize randomized drop rates. Rewards are 100% fixed and guaranteed upon reaching specified criteria:

A. Star Rewards Track

Unlocks explicit customization and gameplay items at fixed cumulative star milestones.

B. Monthly Challenge Milestones

125 Challenge Points: Awards the current month’s Seasonal Cafe location (100% guaranteed). If the player already owns the Seasonal Cafe, a fallback reward of 2,000 Coins is granted.
Every 5 Challenge Points (5, 10, 15...): Grants 1 Challenge Box.

C. Weekly Tournament Leaderboards

Tournament payouts are determined strictly by final leaderboard rank at the end of the competition cycle:

Leaderboard Rank | Guaranteed Coin Reward

Rank 1 (1st Place) | 1,000 Coins

Rank 2 (2nd Place) | 500 Coins

Rank 3 (3rd Place) | 250 Coins

Rank 4+ | 0 Coins

D. Limited Time Offer (LTO) Boxes

LTO Boxes reveal all rewards upfront upon opening. A standard LTO Box grants 3,000 Coins, 60 Minutes Infinite Lives, and 1 Cafe Star (if eligible).

7. Summary of Compliance & Fair Play

No External Odds Manipulation: Virtual item drop rates operate purely on deterministic code algorithms and disclosed adaptive balancing systems. Real-money purchase history does not alter probability tables.
Server & Engine Validation: All reward sampling processes validate player unlock states prior to draw generation to guarantee valid rewards.
