Choose one activity
Repeat a color sequence, check the support for a claim, or follow a lesson on reasoning. Read the instructions before you start.
Get a clear signal
Check the game's result or the quiz's answer explanation. A faster round with more mistakes is different from a more accurate one.
Know what to do next
Retry a rule you missed, revisit the explanation, or move to the next lesson when the idea is clear.
Try a reasoning example
Does the conclusion follow?
A book club sends a reading guide to every member. Asha has a copy of the guide. Someone concludes that Asha must be a member. Before opening the explanation, decide: is that certain, possible, or impossible?
Separate the statements
We know that every member receives a guide. We also know that Asha has one. The claim about her membership is a new statement that needs support.
Try another explanation
Could a member have lent Asha a copy? Could the club have shared it publicly? Neither possibility contradicts the two facts we were given.
Check the missing rule
“Every member gets a guide” does not say “only members can have a guide.” Reversing that relationship adds a rule we do not have.
Read the answer and try a variation
Membership is possible, but it is not certain. The facts allow Asha to be a member or to have received a guide another way. This does not prove that the conclusion is false; it shows that the given evidence does not establish it.
Now add a rule: “Only current members can possess a copy.” If we accept that rule and know that Asha has a copy, membership follows. The useful habit is to name the extra premise instead of silently assuming it.

What a game result can tell you.
Each game's personal rating starts at 1,000 and compares saved rounds with your first result for the same rules and difficulty. A new setup establishes its own reference. Your rating can rise or fall as you play.
A change of 40 points is a change on that game's scale. It is not a 4% improvement in attention, an IQ score, or evidence of a change in everyday abilities. Streaks and reward points count activity.
Designed for momentum
Not a feed. A loop.
No endless library to organise. No perfect routine to maintain. Just one focused action, one clear result, and a reason to return.
Enough time to make a rep. Short enough to make it again.
Feedback that points somewhere useful, instead of ending in a score.
