What the Research Actually Supports
Most cognitive-training products promise to "rewire your brain" or "boost your IQ". Most cannot back those claims. We can not either, so we do not make them. Here is the evidence we read, what it says, and how BrainGym is designed around it.
The honest version
You will get measurably better at the things you practice here: spotting patterns in BrainGym puzzles, sustaining focus through a Treadmill session, holding multiple constraints in mind during a logic problem.
The practice of sitting with a hard problem for several minutes, instead of skipping it, is itself a habit worth building. That habit transfers to real work because habits do, even when "raw cognitive ability" does not.
Difficulty is the product, not a side effect. We deliberately avoid quick reward loops that train fast tapping rather than thinking.
Claims we refuse to make
"Boost your IQ." We cannot back this and the evidence above directly contradicts it.
"Rewire your brain." Every learning experience changes the brain at some level; this phrase is marketing, not science.
"Get smarter at everything." Far transfer of cognitive training to unrelated domains is not supported by current evidence.
"Unlock your hidden potential." This is a feeling, not a measurable outcome.
The studies
These are the load-bearing references. None of them say cognitive training is useless. All of them say its effects are narrower than the marketing in this category usually claims. Read them yourself; the abstracts are open.

How BrainGym is designed around this
If far transfer is unreliable, then near transfer, the kind that comes from practising a specific skill, is what we can honestly aim at. That changes a lot of product decisions:
- Depth over breadth. Per-question timers measured in minutes, not seconds. We would rather you do three hard problems than thirty trivial ones.
- No quick-reward loops. No streaks tied to game-feel, no slot-machine animations, no XP fireworks for tapping fast.
- Honest copy. We track and report the things we can measure (sustained attention, accuracy over time, problem completion), not unmeasurable promises about your raw intelligence.
- Real explanations. Every puzzle has a written explanation of the answer and the reasoning, because the part that transfers is paying attention to how you reason.
Try it before you trust it
The fastest way to evaluate whether this matches the description is to do one session. The guest demo takes about two minutes. No account needed.
