Free online memory and reaction tests. How our games compare with a well-known test site
· 8 min read · Tyamka team
Which reaction and memory tests you can take for free in the browser, how Tyamka's games match the well-known single tests, and where they differ.
Many people who search for free memory and reaction tests end up on Human Benchmark, a website with eight quick tests. If you are looking for an alternative, or just want to know what else exists, this article puts those tests side by side with the games on our site. Some match closely, some only look alike, and a few have no counterpart on either side. The facts about Human Benchmark come from its own pages, checked on 26.09.2026. If you want to start with a test right away, try the reaction time test. It works in the browser on a phone or a computer.
We make Tyamka, so read this as a description from one side. We have tried to describe the other site only by what it says about itself.
What Human Benchmark offers
Its home page lists eight tests: reaction time, sequence memory, aim trainer, number memory, verbal memory, chimp test, visual memory and typing. Each one opens in the browser, and you can start without an account. If you sign up, the site keeps your score history. We found no paid plan. The cookie notice asks for consent for advertising partners. It is in English.
Most of the memory tests there are one run that gets harder until you fail. The sequence gets longer, or more numbers or tiles appear, and your result is how far you got. Results are set against data from other visitors. The reaction time page, for example, says the median reaction time is 273 milliseconds according to the data collected so far.
What Tyamka offers
Tyamka is 15 short games, and four of them are close to the tests people look for on Human Benchmark. Every game has 15 levels that get harder step by step, and each is free up to level 5. You play in the browser or inside Telegram, with no account. Results and bests are saved on your device, and each round is compared with your own previous best on that level, not with other players.
The site is in English and Ukrainian. The website shows an ad after some rounds in the free version. Inside Telegram there are no ads, and any purchase removes them on the website too.
Test by test
| Human Benchmark test | Closest game on Tyamka | How close |
|---|---|---|
| Reaction Time | Go Signal | Same idea, plus levels with choices and a no-go signal |
| Sequence Memory | Button Chain | Close, a sequence that grows by one each round |
| Chimp Test | Hidden Numbers | Close, both follow the same chimpanzee study |
| Number Memory | none | Our Hidden Numbers is a different task |
| Visual Memory | Grid Trail, partly | Different, ours is about order, not a pattern shown at once |
| Verbal Memory, Aim Trainer, Typing | none | No counterpart |
Reaction time
On Human Benchmark a red box turns green and you click as quickly as you can. In our Go Signal a circle appears after a pause of one to four seconds, and you tap it. The pause is random, so you cannot learn the rhythm. After each tap you see your time. The level result is points, and faster taps earn more.
The differences are in the rules. A tap before the circle, or within 0.12 seconds of it, counts as a false start and costs one of three lives, because a reaction that fast is almost always a guess. Levels 4 to 6 have two places for the circle and levels 7 to 9 have four, so you have to choose where to tap. From level 10 a square sometimes appears instead of the circle, and you must not tap it. These levels start again with one place and then move to two and four. The time limit gets shorter within each of these stretches and can grow again when the number of places changes. On a keyboard you press Space or Enter for one place, the left and right arrows or A and D for two, and the arrows or W, A, S, D for four.
Human Benchmark notes on its own page that your computer and monitor add delay to the result. That is true for any browser test, ours included, so a time on your phone and a time on your laptop are not directly comparable. For more on what counts as an average reaction time and why it moves between attempts, see reaction time test average.
Sequence memory
On Human Benchmark buttons light up in a sequence, you press them in the same order, and the pattern gets longer each time you finish it. One mistake ends the test. Button Chain also adds one button to the sequence each round, but you have three lives, and after a wrong tap the right button is outlined and the round goes on. The board has 4 buttons, then 6, then 9, and the show gets faster. Levels 11 to 13 ask for the sequence in reverse, and on the last two levels the buttons change places after the show, so you follow their numbers instead. We wrote about what is known of sequence length in how long a sequence people repeat.
The chimp test and Hidden Numbers
Both go back to a 2007 study by Sana Inoue and Tetsuro Matsuzawa, in which chimpanzees saw numbers on a screen and touched them in order after they were covered. Human Benchmark calls its version a variant of that task. It starts at 4 numbers, adds one each turn, and ends after three strikes. Its page says the chimpanzees consistently beat humans. Later studies by Alan Silberberg and David Kearns (2009) and by Peter Cook and Margaret Wilson (2010) found that people who practised the task could match them, which we cover in the article linked at the end of this section. In Hidden Numbers, numbers appear on tiles. When you tap 1, the rest hide, and you tap the hidden tiles from the smallest up. Levels go from 3 to 9 numbers. From level 6 the numbers also hide by themselves, first after two seconds, and on the last two levels in less than half a second. The study and what people achieve on this kind of task are covered in number memory test average.
Number memory
Human Benchmark's number memory test asks you to remember the longest number you can, and its page says the average person can reliably remember about 7 digits. We have no game like this. Hidden Numbers uses digits too, but you remember where they are, not a string to type. If you like the digit-string test, our article on number memory test tips explains the grouping trick that helps with it.
Visual memory
On Human Benchmark a number of tiles on a board flash white, and you pick the same tiles after they reset. Levels get harder, and missing three tiles on a level costs one of three lives. Our Grid Trail is different. Cards light up one at a time and you tap them in the same order, or on some levels in reverse. The sequence grows from 3 to 8 cards and the grid from 3×3 to 5×5. Both use a grid and both are called visual memory tests, but one asks which tiles flashed and the other in what order. The difference is explained in visual working memory.
Tests with no match
We have nothing like verbal memory, the aim trainer or typing. Human Benchmark has nothing like our focus and logic games, such as the Schulte table, the Stroop test, the maze or the sum puzzle, or our word game.
One long run or separate levels
The two approaches suit different moods.
- One run until the test ends gives you one number quickly, such as how many digits or how long a sequence you managed. It is easy to share and easy to compare with other visitors.
- Fifteen fixed levels start easy and get harder. The rules change along the way, for example with more targets or a signal you must ignore, so each level is a slightly different task. Each level has its own best score, and you can replay any level you have opened.
Neither is a measure of your abilities. A result shows how you did on that task, on that device, at that moment. Being faster at a reaction game does not mean you will be faster at something else, as the research in does brain training work shows.
What is the same and what differs
- Price. Both can be started without paying. We found no paid plan on Human Benchmark. Tyamka is free up to level 5 in every game, and the full version is a one-time purchase with no subscription.
- Account. Neither needs one to start. Sign up on Human Benchmark and it keeps your history. Our games keep your bests on the device, and signing in with Telegram on the website merges your bests from both places, keeping the higher result, and opens what you bought in Telegram.
- Language. English only on Human Benchmark, English and Ukrainian on Tyamka.
- Where. One is a website. The other runs on a website and inside Telegram.
- Ads. Human Benchmark asks for consent for advertising partners. We show an ad after some rounds on the website, none inside Telegram, and none after any purchase.
