Frequently Asked Questions FAQ

Brain Arena is a global cognitive competition platform built around four abilities: processing speed, memory, reasoning, and cognitive control. It lets you experience pure thinking ability through games without relying on language knowledge.

Many brain-training apps are designed for practice, but Brain Arena is designed as an actual competition format. It has a world tournament. Everyone competes on the same problems. Paying does not create a gameplay advantage. Abilities are visualized as measurable scores. Instead of vague training, Brain Arena is built to measure and prove performance.

Yes. It starts from stage 1 and gradually becomes more difficult. Early stages are intuitive, so no special knowledge is required.

Yes. Because the core tasks are mostly nonverbal, players can participate regardless of age or country. Later stages become significantly harder, so adults can also find strong challenge.

No. World Cup results are fully separated from payments. There may be additional features or customization options, but they do not directly affect tournament ranking or score.

There are some elements of luck. For example, daily condition or problem compatibility can influence a result. However, over the long term, more skilled players are designed to remain in higher positions more consistently. It is hard to keep winning by coincidence alone, and repeated play reveals ability differences more clearly.

No, it is different from an IQ test. Brain Arena is not a medical diagnosis tool; it visualizes and gamifies cognitive ability as competition. It still includes overlapping domains such as reasoning, memory, and processing speed.

You are fine to start. It begins with simple and intuitive stages. When you feel "this is harder than expected," that moment can help you notice your strengths and weaknesses.

Choose the game you want to play and challenge stages in order from stage 1. When you clear one, the next stage is unlocked.

Stage is the visible progression number the player advances through (1-99). Level is the internal difficulty tier managed by the system (1-9). As stage number increases, internal level also rises, and speed demand, memory load, and complexity increase step by step.

Yes. You can replay cleared stages as many times as you want. Repeating helps you confirm growth and consistency.

Yes. Each game uses different abilities and rule structures. Reasoning-focused games Memory-focused games Speed-focused games The combination of abilities varies by title.

It depends on the game. Some games end immediately after a mistake. In other games, mistakes are allowed but your time record becomes slower. In every game, mistake handling is explicitly defined in advance.

Basically, there is no fixed time limit. Brain Arena is not about finishing within a countdown; it is a time-record competition that measures how fast and accurately you clear. Faster clear times lead to higher evaluation.

Problems may include random elements. However, difficulty is standardized by level criteria, so it does not become extremely favorable or unfavorable. There is some short-term luck impact, but in the long run, ability differences are designed to appear in results.

A good approach is to return to earlier stages and rebuild stable clears. If you focus not only on speed but also on accuracy and decision consistency, you may find a breakthrough.

Daily Arena is the live competitive mode where players around the world enter the same 24-hour round and solve the same challenge. Separate from normal training, it uses a fixed problem published for that round, so everyone in the same round competes under the same conditions.

Daily Arena is a once-per-day, single-attempt challenge. Once you start, you cannot retry that round. Cleared results are used for ranking and Brain Index updates.

The base score is your clear time. The faster and more accurately you clear, the higher your evaluation. That time is compared with players in the same level range, and converted into a statistically standardized score.

Scores are standardized by difficulty (level). So, "being fast on an easy stage" and "being fast on a difficult stage" are properly distinguished by design.

Brain Index is an indicator that updates your Speed / Memory / Logic / Control profile based on Daily Arena results. It helps show which abilities stand out against a fixed benchmark. It is not an IQ test or medical diagnosis.

SPEED: the ability to judge and react quickly MEMORY: the ability to process while retaining information LOGIC: the ability to detect rules and structure CONTROL: the ability to suppress impulses and act accurately Each game is designed to use these abilities in different proportions.

By checking your ability-specific scores, you can see which abilities are currently strong and which abilities have room to grow. Rather than simply "fast or slow," you can understand yourself as an ability profile.

Repeated play improves consistency and decision speed. However, Brain Arena is designed so that simple memorization alone will not be enough. As core processing ability becomes stable, it leads to long-term score improvement.

Yes. Scores are compared with players worldwide under the same standard. There is no adjustment by country or age, and evaluation is based on fully identical rules.

Brain Index updates when a cleared Daily Arena result is saved. The result screen shows comparison with that day's benchmark time, not the Brain Index itself. Your Brain Index profile becomes available in Profile after the required clear count and global record count are met.

It is Brain Arena’s official competitive event held every month. All players challenge the same stage set and compete for ranking by pure ability.

Yes. Any player with an account can participate. No special qualification or payment is required.

No. Tournament results are fully separated from payment. Practice volume or extra feature access does not directly affect tournament score.

Everyone competes on exactly the same stages Same rules and same conditions Scores are standardized by level criteria This minimizes environmental differences and random effects.

There is some luck impact. Daily condition, concentration, and compatibility with problems can affect outcomes. However, across repeated tournaments, players with stronger ability are designed to stay in top ranks more consistently.

The tournament is one-shot. You get one official attempt only. That single result determines your rank.

Rewards and titles are granted based on ranking. However, they do not affect competitive ability. The tournament is not for gaining advantage, but for proving ability.

You can check results from the ranking screen. You can also view records of top players.

Ranking is determined by total time across all stages within each level. The shorter the total time, the higher the rank.

In Brain Arena, each level (Lv1-Lv9) has an independent ranking. Only players who clear all stages in that level are eligible for that level ranking. Each game also has an ALL ranking based on the combined time for stages 1-99.

If you have not cleared every stage in that level, you will not appear in the ranking. Completing all required stages is the condition to join ranking.

If total time is the same, players share the same rank. Also, if multiple players have the same time as 10th place, all of them are displayed.

As a rule, up to top 10 players per level are displayed. However, when tied ranks occur, the displayed count may exceed 10.

Currently, only top positions are shown. The full ranking list is not displayed.

Rankings are independent by level. Because difficulty differs, direct rank comparison is not made. Evaluation is based on completion time within each level. Within the same game, players can also be compared in the ALL ranking based on the combined time for stages 1-99.

JAM is a point you can earn by meeting specific conditions. As you keep playing, you may receive it at unexpected moments.

Acquisition conditions are not publicly disclosed. To understand what can trigger JAM, please refer to the histories of players who actually earned it. Small discoveries are part of the fun.

Currently, JAM can be used for: Profile icon customization Purchasing specific items JAM use cases are planned to expand further over time.

No. JAM does not affect competitive results. World Cup and ranking are determined only by play results.

No. JAM is a system to expand experience and expression, and does not directly affect cognitive ability or tournament performance.

In the future, possible additions include: Additional items Limited customizations Special experience elements and more. However, competitive fairness will continue to be maintained.

Yes. JAM is the point currency used in Brain Arena. You can earn it from first-time stage clears and friend invites, then spend it on stage unlocks and avatar changes.

Yes. Brain Arena is currently playable for free. Stage progression and participation in the World Cup are also available with no additional fee.

In some free-play contexts, ads may be displayed. We aim to design it so ads do not heavily disrupt gameplay.

At this moment, there is no ad-hide option. We are considering ad-free support in future paid plans.

Currently, there are no paid gameplay features. In the future, we may introduce extensions or options that broaden the experience, but competitive fairness will not be compromised.

At present, specific details and launch timing are undecided. Even if paid plans or additional features are introduced, we will keep a design that does not affect fairness in World Cup and rankings.

Fairness is one of Brain Arena’s most important design principles. All players compete on the same stages in the World Cup Payment does not affect competitive results Scores are standardized by level These keep a structure where ability is reflected correctly.

We operate monitoring and detection measures to prevent misconduct. If abnormal scores or behavior are detected, a player may be excluded from ranking. We maintain mechanisms to protect a healthy competitive environment.

Player data is managed appropriately. For handling of personal information, please refer to the privacy policy.

Some games use random generation, but difficulty is unified by level criteria. It is designed to avoid extreme advantage or disadvantage.

Brain Arena is designed around nonverbal tasks. Its structure reduces gaps caused by language and culture. No adjustment is applied by age.

Because competitive reliability is prioritized. We believe keeping rank unaffected by non-skill factors supports a sustainable competitive culture over the long term.

If the app is closed during play, that stage attempt may become invalid. We recommend playing in a stable network environment.

Depending on network conditions, play results may not be recorded correctly. Please use as stable a network as possible.

If you are logged into your account, your data will carry over. Please confirm login status before changing devices.

Yes. You can proceed from the "Delete Account" button on the settings screen. Please note that deleted data cannot be restored.
