Overflow: Pipe Puzzle

The water is already on its way. You have seconds to build the water a path. Overflow is a pipe puzzle about thinking fast and committing. A countdown runs, the water starts moving, and from then on you are laying track ahead of water that will not wait for you. Fill more of the board and you earn more stars — but every extra tile is another second you are not spending on the route to the drain. HOW IT PLAYS • Tap a tile to move your cursor there, then tap again to lay a pipe. • Or hold and drag to steer — rest your thumb beside the board and it works like a trackpad, so your hand never covers what you are looking at. • A PLACE button sits under the powerups, so the whole game can be played one-handed. • Pieces come from a queue. Hold one back for later, or flush the whole queue when it deals you a run you cannot use. • Hit Fast Forward when you are confident and bank the time you saved. STARS, SCORE AND SECOND CHANCES • Getting the water to the drain clears the level. How much of the board it crossed on the way decides whether you walk away with one star or three. • Score is the finer measure: multiplier pipes raise it, replacing a pipe you already laid costs you, and fast-forwarding early pays a bonus on every tile after it. • Dead-end the water and you are not finished yet — take the rewind, wind the level back and try the junction again. • Every level keeps your best, so there is always a reason to go back to an early one with what you know now. WHAT YOU WILL RUN INTO • Thirty hand-built levels that introduce one idea at a time. • Pressure plates that hold a route open only while the water is sitting on them. • One-way tiles that decide which direction you may enter from. • Multiplier pipes that pay out across the whole level, not just the tile. • Rocks in the way, and a bomb for when there is no way to route the water round. • Freeze, to hold the water still while you think. • Wild, a pipe that connects to whatever it finds. MAKE IT YOURS • Twenty-two water styles, from a clean classic flow to comets, embers and plasma. • Twenty-four board themes. • A global water colour that repaints the pipes, the water and the backdrop together. • All of it paid for with coins you earn by playing. • Coins come from stars, from pickups hidden on the board, and from turning up — a daily bonus that grows the more days you play in a row. NO NONSENSE • No adverts. • No real-money purchases. • No energy timers, no lives, no waiting to play. • No account to create. Sign in to Google Play Games if you want your progress backed up, or do not — the game plays the same either way. BUILT TO BE PLAYABLE • Portrait or landscape, switched whenever you like, mid-level included. • Reduce Motion, in Options, for anyone the moving background does not agree with. • Multiplier pipes carry a printed number as well as a colour, so they read the same whatever your colour vision. • A guided tutorial on your first level, and one-off tips that appear the first time each new idea does. A pipe puzzle is a small promise: here is a problem, it is yours to solve, and nothing is going to interrupt you while you do. Overflow keeps it — just you, the water, and the next piece.
