The games
Thirteen puzzles, rebuilt to be played in short sittings.
Every game ships in Easy, Medium and Hard — Hard unlocks at level 5. Every game keeps a record, fewer moves and less time make for a better one, and every record can land on a leaderboard.
Sudoku
A 6×6 grid where every row, column and 2×3 box holds 1–6 exactly once. Harder means fewer clues.
Lights Out
Tap a tile and its four neighbours flip with it. Turn every light off — 4×4 up to 6×6.
Mastermind
Crack a secret code of coloured pegs from feedback alone. Up to 8 colours across 5 slots.
Tower of Hanoi
Move the stack one disk at a time, never a larger disk onto a smaller one. Six disks take 63 moves.
Simon
Watch the pattern, repeat it, watch it grow by one. Reach round 16 on Hard — and it flashes faster.
Sliding Puzzle
Slide the tiles back into order around the one empty square. The grid grows with the difficulty.
Zip
Draw one path through every cell, passing the numbers in order. 5×5 up to 7×7, with walls in the way.
Patches
Cover the board with rectangles — each clue gives a patch's size and shape. Hard hides most of the shapes.
Crowns
One crown in every row, column and coloured region, and no two touching — not even diagonally. Up to 9×9.
Day & Night
Suns and moons, balanced in every row and column and never three in a line — with = and × signs between cells.
Pixels
Number clues on every row and column reveal a hidden pattern. Up to 10×10, and always solvable without guessing.
Connect
Join every pair of coloured dots, and fill the whole board with pipes while you're at it. Up to 11 pairs.
Three difficulties each
Easy to learn the shape of a puzzle, Hard to earn a place on the board. The difficulty is part of the record.

Inside the app
Every screen, as it actually looks.
Screenshots from the current build — a cool off-white ground, one violet accent, and glow spent only on the things worth wanting.
The loop
What keeps you coming back.
The puzzles are the game. Everything below is the reason to come back tomorrow.
Energy
A run costs energy out of a bar of fifteen, and the bar refills on its own — a fresh one every few minutes. It keeps a session to a handful of sharp puzzles.
Daily tasks
A short list that asks for something specific — win Lights Out ten times, finish under a time — and pays fires, coins and XP when you do.
Chests & loot
Wooden, Iron, Silver, Golden and Platinum — from tasks, from milestones, or bought with coins in the shop. Each opens into items of a rarity.
Fires & leaderboards
Wins earn fires, and fires are what rank you — on the Week, Month, Season and All-time boards. The week's top three take chests home.
Levels & XP
Every finished game moves a bar. Levels release milestone rewards and unlock the Hard difficulty, so the games you play for fun still count toward something.
Gems, skins & collections
Chests drop gems and cosmetics. Keep them to complete a collection, wear them as an avatar, frame or banner, or sell the spares back for coins.
Your account
One account, every device, yours to close.
Logikoo asks for an account so your progress, your loot and your place on the boards follow you from one phone to the next.
Sign in your way
An email address and a password, or the Google and Apple buttons if you would rather skip the form. Either way it is one account.
Progress that follows you
Energy, coins, fires, chests, levels and records live on our server, not on the handset — sign in somewhere else and everything is where you left it.
Leaving is easy
Delete your account from inside the app. You get a 15-day grace period to change your mind, and after that the account and its data are erased.
Logikoo is out now.
