Logic Arena: Daily Puzzles

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.

CHESS, PROPERLY

Chess runs on Stockfish, one of the strongest engines in the world, across four opponents from Rookie to Master. The engine is an optional one-time download, so it never bloats your install if you never play it.
