Calm familiarization, not high-stakes drilling.
A few minutes of practice helps a child feel calm and familiar with reasoning formats on test day. This is about gentle exposure, not anxiety.
The right kinds of practice.
The Practice Lab builds figural, quantitative, and spatial reasoning — the core skills measured by cognitive-ability tests like the NGAT and CogAT.
Encouraging, not punitive.
Puzzles are short and self-contained. Get one wrong and the app offers a calm explanation — not a red X and a penalty.
Three simple steps.
Open the lab
Open the lab in any browser. No account, no password, no app store required.
Pick a puzzle type
Choose a room — spatial, figural, or quantitative reasoning — based on what your child wants to explore.
Practice a few minutes
Short bursts are best. A few minutes of calm practice beats a long, stressful session.
Share a puzzle trail with your class.
Every link below opens one Logica trail directly, on any device, with no sign-in. Post it in Google Classroom or on a class page. A child who hasn’t reached that trail yet can still play it from the link; their own map and stars are unchanged.
- Six puzzles per trail, a few minutes each. Trail 1 is the gentlest; trail 5 is the hardest.
- Where to start: Logica starts kindergarten and Grade 1 at trail 1, Grade 2 at trail 2 and Grade 3 at trail 3. Trails 4 and 5 are a stretch for children who find their grade’s trail easy.
- Logica asks for no names or accounts, and its pages load no analytics or advertising.
- Progress is saved in each browser. On a shared device, children share that progress.

One page per reasoning skill.
Each skill the Lab practices has its own parent-readable page — what the skill is, worked examples, and a link straight into the matching room.
Transition to structured practice.
