Questions, answered. Everything you need to know before you start running through the letters. What is Letter Run? Letter Run is a free 3D scavenger hunt that runs in your web browser. You explore a clubhouse laid out on a sea of waves, whose rooms are shaped like the letters A-N-S-W-E-R C-L-O-U-D. Each room has a mini-game, and winning it earns that room's treasure. It is based on Letter Run by Edgar Allan. How do I move and jump? Use the arrow keys or W, A, S and D to move. Press the spacebar to jump. The letter rooms lie flat on the sea, so you can walk straight onto them. Jump to hop onto furniture. What are the 11 treasures? Laptop, soccer ball, socks, beach ball, mug, record, rocket, picture frame, globe, bunny, and spark. There is one in each room. How do I win a treasure? Step into a room to see a hint. Each treasure floats in a glowing bubble. Step into the bubble to open that room's mini-game, then win it to collect the treasure. If you lose, try again as many times as you like. The rocket's bubble sits on a launch pad. What are the mini-games? The Office (A): Stack the Files. Drop each sliding file box onto the pile. Overhangs get trimmed. Stack 8 to win. Press Space or tap. The Garden (N): Penalty Kicks. The arrow sweeps across the goal. Shoot when it points away from the keeper. Score 3 of 5. Press Space or tap. The Studio (S): Sock Match. Flip two cards at a time to find matching socks. Match all 6 pairs. Click a card, or use the arrows and Space. The Pool (W): Keepy-Uppy. Move the float to keep the beach ball out of the water. Bounce it 10 times. Use the arrows, or move the pointer. The Cafe (E): Perfect Pour. Hold Space, or press and hold, to pour. Let go inside the marked band. Fill 3 cups. Don't overfill! The Music Room (R): Echo. Watch and listen, then play the melody back. Use the arrow keys or tap the pads. Reach 5 notes to win. Outer Space (C): Asteroid Dodge. Steer the rocket left and right to dodge the asteroids. Survive 15 seconds. Use the arrows, or move the pointer. The Gallery (L): Picture Puzzle. Slide the tiles to rebuild the painting. Use the arrow keys, or tap a tile next to the gap. The Study (O): Map Maze. Find a path through the maze to the globe in 45 seconds. Use the arrow keys, or tap where you want to step. The Pet Room (U): Bunny Bop. Bunnies pop out of the burrows. Tap them, or press keys 1โ€“6, to give them a pat. Pat 10 in 25 seconds. The Sky Loft (D): Cloud Hop. Bounce from cloud to cloud and climb up to the spark. Steer with the arrows, or move the pointer. How do I play the mini-games? Most games use the arrow keys and the spacebar, or a mouse. On a touch screen, tap the game or use the on-screen buttons under it. Press Escape or the close button to leave a game at any time. Can I play with or without sound? Yes. Choose "with audio" or "without audio" when you start. You can switch sound on or off any time with the sound button in the top-right corner. The soundtrack is slow and airy, and it shifts as you move between rooms. Does it work on phones and tablets? Yes. On a touch screen, an on-screen pad appears in the bottom-left corner for moving, and a Jump button appears on the right. A keyboard on a computer gives the smoothest experience. Is my progress saved? Yes. The treasures you find are saved in your browser on this device. Open the menu and choose "Reset game" to hide them all again. What do I need to play? A recent version of Chrome, Firefox, Safari, or Edge with JavaScript and WebGL turned on. There is nothing to install and no account to create. Who made Letter Run?
