A LITTLE LOGIC. THREE WAYS TO PLAY.

How to play.

Find the hidden number in every square. All three modes use the same clues, with three attempts per board and one number already given.

01Pick a number. It fills the next empty square, left to right, row by row. Use every number once per board: 1–9 on a 3×3, 1–16 on a 4×4, and so on. Each choice is committed.

02Follow the clues. Clues appear as soon as you choose. Blue ↑ means the hidden answer is higher than your guess. Red ↓ means lower. Green ✓ means correct.

03Fill, submit, refine. Fill every square, then submit. Correct numbers stay locked for your next attempt; earlier clues help you narrow down the rest. On attempt three, the first wrong number ends the puzzle immediately.

Example: 3 gets a blue up arrow because the answer is higher; 5 gets a red down arrow because the answer is lower. Submit, then use 5 and 3 in those squares to solve the board.
Read the clues. Keep the greens. Solve the rest.

Choose your mode.

Classic

BUILD A STREAK

Solve 3×3 boards using 1–9. Every win adds to your streak; losing a puzzle resets it. There’s no timer, so pause between puzzles and come back whenever you like.

Super Soconu

GROW THE GRID

Start at 3×3. Each cleared board adds a row and a column: 4×4, 5×5, and beyond. Every board still gives you just one number and three attempts. There’s no timer; keep climbing until you lose a puzzle.

Speed Soconu

BEAT THE CLOCK

Start with 45 seconds and clear as many 3×3 boards as you can. Each correct number you enter adds +1 second; each cleared board adds +5 seconds. The next board starts immediately. Your run ends when time runs out or you lose a puzzle.

No pause in Speed: the clock keeps running while you read help, switch modes, or leave the game.
