Connect Four

Drop discs, line up four

How to play
  1. Goal. Be the first to connect 4 discs in a row!
  2. Drop a disc. Tap a column to drop your disc to the bottom.
  3. Connect 4. Connect 4 discs horizontally, vertically, or diagonally to win.
Tip: Block your opponent before they connect 4!
Dots & Boxes

Dots & Boxes

Pass & Play or vs Computer

How to play
  1. Draw a line. On your turn, tap the gap between two dots to draw a line.
  2. Take turns. Players alternate drawing one line at a time.
  3. Claim a box. Close the 4th side of a box to claim it — and take another turn.
  4. Most boxes wins. When the grid is full, the player with the most boxes wins.
Tip: Try to avoid drawing the 3rd side of a box — that gives your opponent a free claim.
Ultimate Tic-Tac-Toe

Ultimate Tic-Tac-Toe

Nine boards, one big game

How to play
  1. Nine boards. The board is nine small tic-tac-toe boards inside a big one.
  2. Send your opponent. Your move sends your opponent to the small board matching that cell.
  3. Win a board. Win a small board with 3-in-a-row; if sent to a finished board, play anywhere.
  4. Win the game. Win three small boards in a row to win the game.
Tip: Send your opponent to a finished board and they get to play anywhere!
Sudoku

Sudoku

Logic puzzles · 3 difficulty levels

How to play
  1. Goal. Fill every row, column, and 3×3 box with the digits 1–9.
  2. Select a cell. Tap an empty cell, then tap a number to place it.
  3. Helpers. Use Notes for pencil marks; Hint reveals a correct cell.
  4. Mistakes. Three wrong entries ends the game — play carefully!
Tip: Scan rows, columns, and boxes together — a number often has only one legal spot.
2048

2048

Slide & merge to 2048

How to play
  1. Swipe. Swipe up, down, left, or right — every tile slides that way.
  2. Merge tiles. Two tiles with the same number merge into one, doubling its value.
  3. Reach 2048. Make a 2048 tile to win, then keep going for a higher score.
  4. New game. No moves left? Tap New Game to start over. Your best score is saved.
Tip: Keep your highest tile in a corner — it makes bigger merges much easier.
Block Blast

Block Blast

Clear rows & columns for score

How to play
  1. Place pieces. Drag a piece from the tray and drop it onto the board.
  2. Clear lines. Fill a full row or column and it clears — more room to keep playing.
  3. Score points. Score points for every block placed and every line cleared.
  4. Game over. Game ends when none of your 3 pieces fit anywhere. Beat your best score!
Tip: Keep the board open and flat — don't let gaps pile up in corners.
Hangman

Hangman

Guess the word, letter by letter

How to play
  1. Guess letters. Tap letters on the keyboard to guess what the hidden word is.
  2. Correct guess. A correct letter fills in every spot it appears.
  3. Wrong guess. A wrong letter adds a piece to the drawing — too many wrong guesses and it's over.
  4. Win. Guess every letter before the drawing is complete to win.
Tip: Guess common vowels first (A, E, I, O, U) to reveal more of the word early.
Battleship

Battleship

Sink the enemy fleet first

How to play
  1. Place your fleet. Tap a ship, then tap the grid to place it. Rotate before placing if you need to.
  2. Take turns firing. Tap a cell on the enemy grid to fire. A hit lets you keep tracking that ship.
  3. Sink the fleet. Hit every cell of a ship to sink it. Sink all enemy ships first to win.
Tip: Spread your ships out — clustering them makes it easy for your opponent to sink two at once.
