How much can your BRAIN handle? Not Not puzzle game is the ultimate brain-busting challenge based on logic and orientation. Follow the written instructions to swipe your character towards the correct direction (up, down, left or right) and victory. As you reach higher levels in the game, increasingly complex and varied instructions will require use of both your logic and dexterity for you to succeed. And sorry (not really) for any mental inconvenience this may cause :) Two game modes are available: - in the classic mode, discover a new concept on each level! - in the challenge mode, go as far as possible following more and more complex instructions! ***** "Amazing game!" "NotNot is a fun, challenging, and hilarious game. This will cheat your brain many times, so when you finally finish a level, it's super satisfying. It consists of short levels (sometimes) and its very addicting." _by HKapples_ ***** "This game is epic" "This game is epic. The graphics are great, the game is enjoyable and it a brilliant game. It is quite challenging but is still realy fun. You just got to have good reactions." ---------------- _by a notnot reviewer_ ***** "Creative new mind bending game!" "Give it a try, something different." ---------------- _by JTonzo_
Stack
Read full descriptionHide full description
Stack is a simple, calming one-tap game about building the tallest tower you can. A block slides back and forth across the top of your tower. Tap to drop it. Whatever hangs over the edge is sliced off and falls away, so the next block is smaller. Miss completely and the run is over. Land a block perfectly and it snaps into place with no loss. Chain six perfect drops in a row and your blocks start growing back, so a steady hand can keep a tower going for a very long time. FEATURES • One-tap controls — easy to learn, hard to master • Perfect-drop combos that grow your blocks back • A sky that shifts colour as your tower climbs • 19 block skins with their own colours and patterns, from Leaf and Candy to Marble and Hologram • Earn coins as you play and spend them on skins — no purchases, no ads • Special skins unlocked by reaching new best scores • Works offline, no account needed How high can you go?
