BRAIQTH: Vocab & Study Battle

Can you solve this in 10 seconds? Answer 4-choice questions to defeat enemies in 13 subjects, from irregular verbs to science. Battle friends online — no account needed.

The more you learn, the stronger you get.

BRAIQTH turns studying into a battle. Every question you answer deals damage to the enemy — answer faster and keep your combo alive to hit harder. One more question is never quite enough.

■ 13 subjects

• Irregular verbs (English)
• Vocabulary battles (English, Chinese, Malay)
• Sentence battles (English, Chinese, Malay)
• Fill-in-the-blank battles (English, Chinese, Malay)
• Math
• Science
• Geography and history

■ 15 seconds of focus Each question has a 15-second limit. The screen pulses red in the last 5 seconds, and answering within 3 seconds shows your exact time and deals 1.5x damage. Questions you get wrong come back later in the same battle, so nothing stays half-learned.

■ Collect as you learn Win a battle and a treasure chest opens. There are 48 weapons across four rarities; duplicates turn into shards you can spend, with coins, to level a weapon up. Your avatar combines 10 characters with faces, items and pets, and evolves as your level rises.

■ Compete with friends

• Online battles: share a room code, or match at random
• Weekly, monthly and per-subject rankings

• Friend list

■ See your progress Accuracy, day streaks, average answer time, a 14-day history and your strongest and weakest subjects, all in plain numbers and charts.

■ Four languages Japanese, English, Simplified Chinese and Malay. Pick your native language and the app builds questions between it and the language you want to learn.

■ Accounts are optional Every subject is playable without an account. Creating one adds progress backup, syncing across devices, rankings, online battles and friends. Sign up with an email address and a password.

■ About ads The only ads are optional rewarded videos in the Shop ("watch a video to earn points"). There are no ads during battles or on result screens. Ads are non-personalized and rated for all audiences, and we never track users across apps.
