Core cognitive drills for attention, memory, logic, and estimation.
Spot two targets in a rapid stream of flashing items.
Memorize a lit pattern, then recall it perfectly.
Match position and letter from N steps ago.
Watch for rare targets in a long stream of distractors.
Complete 4x4 logic grids with row and column constraints under time pressure.
Cycle through quantity, timing, and length estimation with calibrated feedback.
Track directional sequences on a hidden grid, then report your location and heading to start.
Evaluate chained AND, OR, NOT, and XOR circuits from live input bits.
Drop number blocks and clear adjacent pairs that sum to the target before overflow.
Run timed estimation rounds from the imported Fermi seed bank, with unit-tagged answers and confidence tracking.
Judge each word as seen-before or new while balancing speed and accuracy across a mixed memory stream.
Name the correct color under interference with selectable twists: rule pulses, memory echoes, emotion spikes, or mixed mode.
Skill-focused symbol systems and encoding practice.
Lexical search, semantic reasoning, and language pressure loops.
Build as many valid words as possible from a generated 6-12 letter set and score by word length.
Drop weighted letter blocks and clear horizontal or vertical dictionary words in any reading direction.
Find the hidden word by semantic closeness, with each guess ranked against the full dictionary.
Replace a highlighted word with context-matching synonyms and inspect four separate semantic closeness metrics for every guess.
Inference, argument, and route-solving challenges.
Ask yes/no questions about an abstract scenario and infer the hidden explanation.
Evaluate claims and quickly identify the strongest counterargument from plausible alternatives.
Predict the correct boundary exit from a given entry in either paired-path mazes or classic branching mazes.
Open-ended systems for creative discovery and experimentation.
Focus Lab is built to help people practice how they learn to solve cognitive puzzles, not to promise a direct transfer to general intelligence.
Research often shows that many brain-game skills stay narrow to the trained task. This project accepts that limitation. The goal is different: build better personal problem-solving habits under pressure.
We train strategy discovery: finding shortcuts, heuristics, mental representations, and repeatable routines that work for each person.
Treat every game as a lab. Try a method, observe your mistakes, refine your method, and keep what reliably improves your speed and accuracy.
