Chainfall Block Puzzle

From the App Store Source

Four blocks of one colour, touching, and they're gone. Then whatever falls into the gap can match as well — that's a chain, and chains are where the points are. Chainfall is a falling-block colour matcher built around that one idea. Pieces drop into a six-by-twelve well, you steer and rotate them, and the board pays you back for setting up a collapse instead of just clearing what is in front of you. THREE WAYS TO PLAY Survival — three minutes on the clock, and every clear buys more of it. The pieces keep getting faster, so the only way to stay ahead is to clear better; the longer you last, the more each clear is worth. There is no ceiling on the clock — how long a run goes is up to you. Endless — no clock at all. Set the falling speed yourself with the slider, change it whenever you like, and it stays exactly where you put it. Faster pieces score more, so it is a wager as much as a comfort setting. Puzzles — fifty fixed boards with a goal and a piece budget. Three stars means solving one efficiently, not quickly; there is no timer to rush you. BLOCKS THAT CHANGE THE BOARD Wood never matches, so it has to be cleared another way. The two clearing blocks — one sweeps a row, one sweeps a column — fire when you tap them, which makes deciding when to spend one part of the game. A REASON TO COME BACK Three tasks a day, drawn fresh each morning. They sit over the whole game rather than inside one mode, so progress counts whether you are racing the clock, playing endless or working through the puzzles. BUILT TO BE PLAYABLE Colour symbols mark every colour with its own shape, so the board can be read without relying on hue. Menus scale with Dynamic Type. Sound effects and music have separate switches, and the music never plays over what you are already listening to. WHO IT'S FOR Casual puzzle players who want something to pick up for a minute or sink into for a long run.
