Free online brain games

Echo Pads
Watch the pads light up, then play the sequence back. It grows every round.
Quick Math
True or false? Snap judgements on equations, against an ever-shorter clock.
Color Clash
The word says one colour, the ink shows another. Tap the one you're asked for — fast.
Odd Hue
One tile is a slightly different shade. Find it before time runs out.
Grid Recall
Some tiles light up for a moment. Remember them and tap them all back.
Count Up
Tap the numbers in order, 1 to N, as fast as you can. Levels keep growing.
Pair Flip
Memorise the board, then flip cards to find every pair before the shared clock runs out.
Hi-Lo Cards
Higher or lower? Guess the next card before the timer runs out and build a streak multiplier.

Each tap flips a light and its neighbours. Switch the whole grid off within par and the clock.
Safe Steps
Read the numbers, mark the hidden hazards and clear every safe tile before the clock runs dry.

Drop discs and connect four in a row before the CPU — every win makes it think deeper.
Flip Disc
Outflank and flip discs on an 8×8 board, grab the corners and beat ever-smarter CPUs.
Match Back
Spot when a symbol matches the one N steps back — 1-back, then 2, then 3, ever faster.
Color Mix
Mix red, yellow, blue, white and black paint drops to copy the target colour as closely as you can.
Clock Rush
Read the clock hands and pick the right time fast — then flip it and add the minutes in your head.
