brainGO FAQ: Go, Capture Puzzles, Kids, Seniors — Answered
⏱ Read ~5 min · Updated July 2026 · Part of: Learn Go
The questions people actually ask about Go, 4×4 capture puzzles, and brainGO — answered plainly and honestly.
Is Go really the hardest game in the world?
No — that's Go's reputation, not its reality. Go has almost no rules (essentially: surround a stone to capture it). What's deep is the strategy that grows from those rules, not the rules themselves. A beginner can finish a first 4×4 puzzle in under a minute. See Learn Go.
What age can start playing Go?
Very young. Because Go has no numbers and no reading, a pre-literate child (around 4+) can play a 4×4 capture puzzle after one demonstration. The tiny-board "Capture Go" tradition is exactly how generations of children have entered the game. See Go for kids.
Is Go good for seniors?
It can be a great daily mental exercise — visual, no number anxiety, short rounds, calm pacing. We say it keeps your mind active; we don't claim it prevents dementia, because the evidence is inconclusive. Memory concerns belong with a clinician. See Go for seniors.
Do I need a board or to buy anything?
No. brainGO runs in a web browser — no app install, no physical board. The 4×4 puzzles are generated by an exact solver, so every "winning move" is provably correct.
Is 4×4 Go "real" Go, or a toy?
It's real Go, distilled. The full game is 19×19 with territory and scoring. But the load-bearing skill — reading liberties and captures a few moves ahead — is pure and present on a 4×4 board. That's why teachers worldwide use "Capture Go" (first to capture wins) to start beginners. brainGO takes that to its extreme. See Capture Go training.
Does brainGO use Chang Hsu's 4-road Go puzzles?
No. The puzzles are 100% generated by our own solving algorithm — every board is exhaustively searched and the winning moves are provably correct. We don't use anyone's copyrighted puzzle collection; we were inspired by the teaching philosophy of tiny-board capture Go, not by any specific puzzle set.
Will brainGO prevent dementia or make me smarter?
We won't claim that. Brain games are often marketed as preventing cognitive decline, but the science is inconclusive. What we can honestly say: a daily puzzle keeps your mind active, it's satisfying, and it's a better use of a few minutes than scrolling.
Is brainGO free?
The daily puzzle is free. There's an optional Family Plan (a child or family member pays so a senior parent gets unlimited play and an activity log) and B2B licensing for care facilities. See Brain games to keep your mind active.
Where do I start?
One puzzle. Place a stone. The companion character shows you the rest.
