Falling Blocks is the purest puzzle game ever designed. Shapes drop from the top of the well, you rotate and slide them as they fall, and any row you fill completely disappears. Let the stack reach the top and it is over. That is the entire rulebook, and it has kept people playing for forty years.
What makes it endless is that the game never gets easier and you never quite catch up. The pieces come faster, the stack creeps higher, and every decision you make about where to drop a shape constrains the ones after it. You are not really clearing lines, you are managing the consequences of your own earlier choices.
Keep the stack flat. A level surface accepts almost any shape, while a jagged one leaves gaps you cannot fill later. Every time you are tempted to stack a piece somewhere awkward, ask whether it makes the surface flatter or bumpier, and prefer flatter.
Do not dig a deep well unless you have to. Leaving one column empty to wait for a long straight piece is a famous strategy, but it is a gamble: if the piece does not arrive, the stack builds up around a hole you cannot use. Only keep a well open when the rest of your surface is clean.
Fill holes as soon as they appear, not later. A covered gap is dead space that will haunt you for the rest of the game, because everything stacked above it has to come off before you can reach it. One buried hole early often decides how the whole game ends.
Think about the next piece, not just the current one. If you know a shape is coming that only fits in one place, leave that place open. Playing one piece ahead is the single biggest jump in skill this game offers.
Fill an entire horizontal row with blocks and it vanishes, dropping everything above it down.
Yes. The drop speed increases as you progress, which is the whole difficulty curve.
When the stack of blocks reaches the top of the well and a new piece cannot enter.
Rotation works wherever there is room for the shape to turn, so plan your rotations before the piece is jammed against the edge.
No. Falling Blocks runs entirely inside this page, so it starts the moment the page opens. There is nothing to download, no plugin, and no account to create.
