Focus Games
Short, simple brain games that stay in your browser. Large tap targets, offline after first load, and best scores saved only in localStorage. Sound stays off; scores stay local.
Memory Match
Flip cards on a 4×4 board and find matching pairs. Beat your best move count.
Sequence Recall
Watch the pads light up, then tap the same pattern back. Climb as far as you can.
Number Slide
Classic 15-puzzle on a 4×4 grid. Slide tiles into order with as few moves as possible.
Word Scramble
Unscramble a common English word, then hit Next for another. Keep a streak going.
Reaction Tap
Wait for gold, then tap. Five rounds; best average time stays on this device.
Tap Order
Numbers 1–9 are shuffled on a 3×3 grid. Tap them in order as fast as you can.
Color Clash
A color word in the wrong ink. Tap the ink color, not the word. Best streak stays local.
Odd One Out
Four tiles: three match, one differs in shape or color. Tap the odd one. Best streak stays local.
Higher or Lower
A number from 1–99. Guess if the next is higher or lower. Best streak stays local.

Even or Odd
A number from 1–99. Tap whether it is even or odd. Best streak stays local.
Count the Dots
A few dots flash briefly. Tap how many you saw. Gets a little faster as your streak grows.
Middle Arrow
Five arrows in a row. Tap the way the middle one points and ignore the rest. Quick focus training.
Same as Last
Shapes appear one by one. Tap Same if it matches the previous shape. A gentle working-memory warm-up.
Light Recall
A few cells flash gold. Tap every one you saw. One more cell each level, from 3×3 up to 4×4.
Go Stop
Gold means tap. Muted means wait it out. A go/no-go drill that tightens as your streak grows.
Turned or Flipped
Two shapes side by side. Is the second rotated, or mirrored? A quick mental-rotation drill.
Spot the Change
A grid of shapes blinks off and back on with one cell changed. Tap the one that changed.
More Dots
Two panels of dots flash up. Tap Left, Equal, or Right for the side with more — the gap narrows as you go.
Glow Grid
Twelve-level logic puzzle. Each tap flips a cell and its neighbours — light the whole grid near par for a high score.
Echo Path
Watch a path wind across the grid, then trace it back. Stages grow longer, grids widen, combos build your score.
Number Forge
Combine number tiles with + − × ÷ to hit the target. A 15-puzzle Journey or a 2-minute Blitz, with par bonuses and hints.
Circuit Link
Turn wire tiles until every lamp is wired back to the gold core. A 12-circuit Journey, a 3-minute Blitz, and a Daily board.
