Logic Arena: 19 Logic Games

19 hand-built logic puzzles in one app — no fluff, no filler, no forced timers.

Every puzzle is generated fresh and checked to have exactly ONE solution before you ever see it. No guessing, no dead ends, no reused boards.

ALL 19 GAMES

• Sudoku — the classic 9x9. Digits 1-9 once per row, column and box.
• Kakuro — a number crossword. Every run adds up to its clue, no digit twice.
• Futoshiki — a Latin square governed by greater-than arrows.
• Slitherlink — draw one closed loop that obeys every number.
• Calcudoku — a Latin square in arithmetic cages. Hit every target.
• Bridges (Hashi) — link every island into one network. No bridge may cross.
• Skyscrapers — place the heights so each edge number counts what you can see.
• Shikaku — split the grid into rectangles. Each number is its own area.
• Binary Grid — fill 0s and 1s. Balanced, never three in a row, every line unique.
• Crown Grid — one crown per row, column and region, and none may touch.
• Sun & Moon — balance suns and moons and obey the = and x clues.
• Magic Square — place every number so rows, columns and diagonals share one sum.
• Math Cross — fill the blanks so every across and down equation is true.
• Number Match — clear pairs that match or sum to ten.
• Zip Trail — one line through every cell, hitting the dots in order.
• Cipher Quote — crack the substitution cipher and reveal the quote.
• Mastermind — crack the hidden 4-colour code before your guesses run out.
• Endless Mines — sweep mines across infinite sectors and chase a high score.
• Chess — play the classic against four levels of opponent.

WHY PLAYERS STAY

• Genuinely offline. Every puzzle is built on your device — play on a plane, on the underground, anywhere.
• One guaranteed solution. Solvable by logic alone, always.
• Levels that keep climbing. Boards grow and clues thin out as you improve.
• Trophies weighted by difficulty, so a hard game counts for more than an easy one.
• Stuck? Take a hint. Nothing is ever a dead end.
• Full rules and worked examples inside every game.
• Eight languages: English, Hindi, Spanish, Portuguese, French, German, Arabic and Indonesian.
