Memory
Number Memory
The classic digit span test. A number flashes up, you type it back — and it gets one digit longer every level. How many digits can you hold?
Verbal Memory
Words appear one at a time — has each one been SEEN before, or is it NEW? Keep as many words in working memory as you can with three lives.
Visual Memory
Tiles flash on a grid, then disappear. Click them back from memory. The grid grows every level — one of the best tests of visual working memory.
Sequence Memory
Watch the tiles light up in order, then repeat the sequence. It grows by one step every level — one slip and it's over. How far can you go?
Memory Test
Evaluate your short-term, long-term, visual, verbal, working, and sequential memory through a comprehensive 48-question assessment.
Attention & Speed
Reaction Time
Wait for red to turn green, then click as fast as you can. Five rounds, average score in milliseconds. The average person manages about 270 ms.
Stroop Test
The word says BLUE but it's printed in red — answer the ink colour, not the word. A classic psychology test of attention and inhibition.
Processing Speed
Two strings of symbols — same or different? Answer as many as you can in sixty seconds. A pure test of mental processing speed.
Concentration Test
Digits flash past — press for every number except 3. Two minutes of sustained attention where the hardest part is doing nothing.
Typing Speed
Sixty seconds against a fresh passage every day. Live accuracy highlighting, words-per-minute score and an accuracy percentage.
Reading Speed Test
Read a passage at your normal pace, answer comprehension questions, and get your words-per-minute score adjusted for understanding.
Reasoning
IQ Test
Measure your cognitive abilities across pattern recognition, logical reasoning, spatial awareness, verbal comprehension, numerical ability, and abstract thinking.
Pattern Reasoning
Assess your fluid reasoning with visual matrix patterns, sequence completion, odd-one-out puzzles, logical deduction, and transformation rules.
Problem Solving
Test your logical reasoning, lateral thinking, strategic planning, analytical skills, and creative problem solving across 25 challenging questions.
Verbal Reasoning
UK-style verbal reasoning in the spirit of 11+ and employer assessments: synonyms, analogies, letter codes, odd one out, and True/False/Cannot Say.
Numerical Reasoning
Percentages, ratios, data tables and money problems in pounds — the maths skills UK employer assessments and entrance exams actually test.
Cognitive Skills Profile
