About Synapse: Brain Games & Puzzles
43 brain games for training. No ads. No account. Works offline.
Most brain games interrupt you with adverts every other round. Synapse has none, and never will. There is no account, no sign-up and no tracking, and the whole app runs on your device.
Every brain game gives you five levels free. If you want the harder ten, there is one optional purchase — paid once, no subscription.
WHAT'S INSIDE
43 hand-built brain mini-games across five skill areas:
• MEMORY (9) — Shopping List, Strange Signals, Hidden Ghosts, Pass the ball, Secret code, Phone number, Color recall, Fingerprints, Magic House
• ATTENTION (11) — Arrows, Silent Space, Crime scene, Identical items, Treasure hunt, Missing number, Tricky patterns, Color match, Lost & Found, One Man Out, Peripheral Vision
• MATH (7) — Math audit, Missing operator, Basic math, Tasty Fractions, Math crossword, Math Chain, Which Is More
• LOGIC (7) — Odd one out, Robotic Flows, Tower of Hanoi, Spy Anagrams, Tap away arrows, Twins Connect, Number Match
• SPEED (9) — Reaction, Find color, Swipes, Colored cells, Schulte table, Disjunction, Pattern Compare, Number Hunt, Number Pairs
HOW IT WORKS
• A daily workout picks three brain games for a short session of about seven minutes
• Every game has 15 levels that unlock as you improve, so it keeps getting harder
• Levels 1 to 5 are free in all 43 games — that is a lot of game before you decide anything
• Track your progress with skill levels, personal bests and 43 mastery badges
• Build a daily streak to keep yourself consistent
• Back up your progress to a file at any time, and restore it on a new phone
WHAT IT DOES NOT DO
• No adverts of any kind
• No subscription — the optional unlock is a single payment
• No account, no sign-up, no email
• No analytics and no tracking
• Your progress stays on your device
• Plays entirely offline. The network is used for one thing only: confirming a purchase or restoring one you already made
A NOTE FROM THE DEVELOPER
I built Synapse - brain games, because I wanted to spend my idle minutes on something better than endless scrolling. The brain trainers I tried were genuinely good, but the adverts and expensive subscriptions wore me down — some days I watched more adverts than I played.
So I made the app I wanted to use. The first five levels of every game are free because that is enough to know whether you like it, and the one-off unlock is there because a one-person project still has bills. No adverts, no subscription, no data collection. That part is not changing.
If you find a bug or have an idea for a game, get in touch through freebraingames.net. You can try the games in your browser there too.
Enjoy the training your brain.
