[FREE FOREVER] PUZZLE GAMES — The Lumosity Killer Game Pack With No Ads, No Subscription, No Tracking
[FREE FOREVER] PUZZLE GAMES — The Lumosity Killer Game Pack With No Ads, No Subscription, No TrackingI got fed up with Lumosity, Elevate, Peak — all of them. Paywall on day 3, ads between every screen, $89/year to unlock the same Sudoku you can do on a napkin. Bullshit.
So I built Puzzle — 108 brain games stacked into one Android app. Free, no ads, no subscription, no tracking, no signup. Works offline forever.
The 108 games, sorted
| Category | # | A taste of what’s in it |
|---|---|---|
 Attention |
25 | Stroop Test, Schulte Table, Object Tracking |
 Logic |
22 | Minesweeper, Nonograms, Einstein Riddles, Sudoku |
 Math |
15 | 2048, Mental Abacus, Arithmetic Sprint |
 Memory |
17 | N-Back, Corsi Blocks, Memory Palace |
 Spatial |
13 | Mental Rotation, Symmetry, Paper Folding |
 Word |
16 | Cryptogram, Word Mastermind, Verbal Analogies |
These aren’t made-up app trivia — they’re the actual tests psychology labs use to measure brain function. Stroop, N-Back, Corsi — real research tools, just wrapped in a UI that doesn’t look like a tax form.
Why this isn’t another reskin
Level 1 → 100 XP grind. Hitting “Eternal” rank takes 1 million XP. Going to take you a damn while.
Streaks per game + one super-streak across everything. Miss a day, it dies. Brutal, but it works.
Buttons that feel physical — small phone buzzes when you tap (haptics — the same vibration your keyboard does), elastic animations, surfaces that sink when pressed. Not the usual cardboard mobile feel.
Zero trackers, zero ads, zero data collected. I literally can’t see what you play. Code’s open — anyone can verify.
