Odds Disclosure

This page lists the odds for the paid feature in BLUECHIP STAR whose result is decided by chance, and explains paid items that change success chances in the game. The app's screens are in Korean only, so names are written as English (Korean).

Bluechips (블루볼) are the game's virtual currency. Bluechip packages are sold through the Apple App Store and Google Play, and the price in your currency is shown by the store before you buy.

1. Identity Reroll (정체성 재추첨)

Identity Reroll is the only paid item whose result is decided by chance.

• Price: 90 Bluechips per reroll.
• What is drawn: one identity for your player and, based on that identity, a new starting value and potential for every ability item. The draw happens on our server.
• Limit: up to 3 rerolls per career slot. Your account's total is also capped at 3 × (the number of unlocked career slots + the number of careers that retired or were deleted after finishing a season).
• Free first draw: when you create a new career, the free identity draw uses the same odds as a reroll.
• Shown in the app before you pay: the same odds appear in the odds table on step 3 of career creation, and on the Check before reroll (재추첨 전에 확인) sheet. That sheet shows every candidate, the odds by band, the starting ability and potential ranges, the price, and your remaining rerolls, before the pay button.

Step 1. Band

On average, a Rare identity comes up once every 12.5 draws.

Step 2. Identity within the band

Every candidate in the drawn band has an equal chance. Candidates come from the pool for your position: pitchers use the pitcher pool, and catchers, infielders, and outfielders use the fielder pool. The chances below combine steps 1 and 2.

10.67% is rounded. The exact value is 32% ÷ 3 = 10.666...%. Each pool adds up to 100%.

Step 3. Starting abilities and potential

Each identity has fixed strength and weakness items. For every ability item, the starting value and the potential are each drawn as a whole number. Every number in the range has an equal chance, including both ends.

• Pitcher ability items: Velocity (구속), Stuff (구위), Control (제구), Breaking Balls (변화구), Durability (내구), Recovery (회복력), Mental (멘탈).
• Fielder ability items: Contact (컨택), Power (파워), Batting Eye (선구), Baserunning (주루), Defense (수비), Throwing (송구), Durability (내구), Recovery (회복력), Mental (멘탈).
• Some identities list strengths or weaknesses that are not ability items, such as pitch mix or growth speed. These do not change the ranges above.

Strength and weakness abilities by identity

Each identity decides which abilities use the strength and weakness ranges above. Abilities not listed use the normal range. Five-Tool uses the same range for every ability.

2. Paid items that change success chances

The items below are not random items. What you get is fixed. We list them here because they change the chance of results in the game.

Luck Boost (운 쌓기)

• Price: 30 Bluechips, or free by watching a rewarded ad.
• Where: Classic and Challenge modes, on event cards that show both a success chance and a failure chance. Once per card.
• Effect: the new success chance is the higher of the current chance p and p + 10 percentage points, capped at 90%. In other words, max(p, min(90%, p + 10 points)).
• Current event cards have base success chances from 25% to 75%, so today a Luck Boost always adds exactly 10 percentage points, for a result between 35% and 85%.
• The result uses a single random roll. The boost only raises the success threshold, so it never turns a success into a failure.
• Limit: once per amateur phase and once per college phase. In the pros, per season: twice in Focus mode (집중 모드), and once in Normal (일반) and Express (익스프레스) modes.
• If a boost you paid for is not applied, the Bluechips are returned.

Training Success Guarantee (훈련 성공 보장)

• Price: 250 Bluechips. Up to 20 per season.
• Effect: for 7 in-game days, training succeeds 100% of the time.
• Without it, the base success chance depends on training intensity: Light (가벼움) 85%, Normal (보통) 70%, High (높음) 60%, Limit (한계) 50%. Each point of condition adds 1 percentage point, and the result is kept between 0% and 100%.
• The shop card shows each intensity's base chance, before the condition adjustment, next to 100%.

Extra Training (추가 훈련 개방)

• Price: 125 Bluechips. Once per day.
• Effect: adds one training session. Its success chance follows the base chances above.

3. Other chance in the game (for reference)

These are part of normal play and are not sold.

• Critical results: after an event's success or failure is decided, a separate 15% chance makes it critical. A success becomes a great success (+1), and a failure becomes a great failure (−1). Luck Boost does not change this 15%.
• Training great success: 1%.

4. Paid items without chance

Bluechip packages, the Daily Pack, cosmetic items, bundles, and all other items bought with Bluechips give fixed contents. Buying them does not involve a random draw.

5. Changes

The odds on this page are as of October 29, 2026. If the odds change, we update this page and the app together.
