How to play Neon Stack
Neon Stack is a survival score game. A stationary base sits on the field. Each new block slides sideways above it. Your job is to set that block down on the overlap. There is no finish line and no combo bonus.
Controls on phone and computer
Select Play. Tap or click the play area, or press Space, to place the moving block. One intentional press places one block. Holding Space, or a repeated key event, does not place another. Space does nothing while you are typing in a field or while a button or link is focused, so it will not place a block when you activate Pause or the name box. Placement is ignored before Play, while paused, and after the round ends.
Overlap, perfect snaps, and scoring
The play field is 240 units wide. The base starts at 72 units wide. Overlap is the shared horizontal span: the right edge that is farther left, minus the left edge that is farther right, and never below zero. An exact edge touch is zero overlap and ends the round, the same as a complete miss. Any positive overlap trims the overhang and keeps a block centred on that shared span. The next block uses that trimmed width. If the moving block’s left edge is within 3 units of the block below, it snaps into line and keeps its full width. That 3-unit tolerance is measured in these field units. Every successful placement, including a snap, scores one point. The block starts at 78 units per second and gains 5 units per second after each point, up to 168. The view follows the tower. Pause, the score, and the name box stay where they are. A trimmed piece may fall away as decoration. It does not hit the tower or change the score, and only a few of those pieces are kept. There is no wind, tipping, or collapse. The round ends only when a placement has no overlap. Your best score stays in this browser. A name is optional. Play again or Close saves the public score once if you entered a name, and saves nothing if the name is empty. Leaving the pause screen does not submit a score.
Tips
- Line the moving block up with the one below. A snap within 3 units keeps your width.
- Place a little earlier once the block is near full speed. It does not wait between frames.
- Ignore the falling offcut. Only the overlap you kept matters for the next block.
