Play Corflex

on corflex.gg

Corflex is a browser site of 20 quick brain tests, from remembering sequences and grids to matching a pitch or reproducing a colour. Every day each mode has a challenge with the same seed for everyone and one attempt, scored out of 50, so you can compare yourself on that mode's daily leaderboard.

About Corflex

Corflex calls itself a brain training platform. It has 20 modes, each built around one skill: Sequence and Grid test ordered and spatial memory, Rhythm and Reflex test timing, Chroma asks you to reproduce a colour, Harmony to match a pitch, Mirror and Maze to work in space, Glyph and Transform to spot rules, and so on. Every mode follows the same loop: you see or hear something, then answer from memory, over five rounds scored from 0 to 10 for a total of 50.

The daily challenge is the shared part. At midnight UTC every mode gets a new challenge, generated from one seed that all players share, and you get one attempt at each. The day's results go on a daily leaderboard per mode, and the home page tracks how many of the 20 you have done and how long is left. Dailies are always on Easy difficulty.

Outside the dailies there are free solo plays at Easy and Hard, a weekly Hard tournament, party rooms where friends play the same puzzles from a link, and a Brain Score that adds up your best result in every mode. No account is needed; an anonymous ID keeps your scores in the browser, and signing in with Google or Discord syncs them.

The site is free with ads. An optional Premium subscription adds a third difficulty, Apex, with a twist on each mode, plus its own leaderboard and profile options. Most modes use sound, so headphones help.

How to play Corflex

Open Corflex and pick a mode from the day's list.
Watch, listen or read the prompt for the round, such as a sequence of tiles, a colour or a tone.
Answer from memory: repeat the sequence, set the colour or pitch, or respond as the mode asks.
Play the mode's five rounds; each is scored from 0 to 10.
Your total out of 50 goes on that mode's daily leaderboard, and you move on to the next mode.

Tips

Use headphones; Rhythm, Harmony, Melody and several other modes depend on sound.
You only get one daily attempt per mode, so warm up on a free solo play first.
Do the modes you are weakest at early in the day while you are fresh.
The day turns over at midnight UTC, so check the timer on the home page before starting late.
