LeKha Brain Cup rules

The Brain Cup is a monthly competition on LeKha Games organised by LeKha. It is free to join; no purchase is required.

1. Period

Each calendar month is one season, in Vietnam time (00:00 on the first day to 23:59 on the last day).

2. Who is ranked

  • Signed in with a LeKha account that has a customer profile (Lộc wallet).
  • Both e-mail and phone number verified.
  • At least one level won and verified by our servers during the month.
  • Not LeKha staff; no breach of these rules.

3. Points

  • First win of a level: 10 points per star
  • Daily challenge: up to 100 points (your best 5 challenges per day)
  • Weekly challenge: up to 300 points
  • A new friend you invited plays and wins: +100 points (up to 10 friends a month); your friend gets +50

Points are recalculated by LeKha's servers from each run; scores shown in the browser are never used for the ranking.

4. Ranking

More points rank higher. On equal points, whoever reached that total first ranks higher. The leaderboard only shows nicknames of players who chose to be shown.

5. When prizes unlock

A month's prize is awarded only when the month has at least 1.000 eligible players. Every further 1.000 eligible players add one more prize (at most 20 prizes a month), awarded to the highest-ranked players.

6. Prize

Each prize is a LeKhaMart shopping voucher worth 2.000.000₫: 4 uses, each taking 500.000₫ off an order from 1.000.000₫, valid for 180 days from issue.

One use per order. A cancelled order gets its use back. The voucher is tied to the winner's account, is not transferable and cannot be exchanged for cash.

7. Review and award

After the month ends, LeKha reviews the results before announcing winners. Abnormal play (automation, multiple accounts, fake invites) may be removed from the ranking.

A player can win at most 2 months in a row; if they top the ranking again, the prize goes to the next player.

8. Recognition and personal data

Only nicknames are shown, and only with consent; LeKha never publishes real names, photos or phone numbers. Data is processed under Decree 13/2023/ND-CP; point details are kept for 13 months.

9. Other terms

LeKha may change these rules for future months and will announce changes on this page in advance. For questions, contact LeKha customer care.
