Néon Stack

About this game

Néon Stack is a falling-block game in a polished retro-neon skin, in the great tradition of arcade stacking puzzles. The idea is crisp and fiercely addictive: pieces made of four squares — the seven classic tetrominoes, shaped like a bar, a square, a T, an L, a J, an S and a Z — drop one at a time into a well ten columns wide and twenty rows deep. Your job is to slide them left or right and rotate them to slot them in as tightly as you can. The moment a horizontal line is completely filled, it clears in a burst of light and everything above drops one row: that is the heart of the game, and clearing several lines at once is what makes your score explode. Completing four lines simultaneously sets off the famous QUAD, the most rewarding and most spectacular move in the game. The score rewards efficiency and nerve: one line pays a hundred points, two lines three hundred, three lines five hundred and four lines eight hundred, all multiplied by your current level. You also earn points by dropping a piece faster (soft drop) or instantly (hard drop). Every ten lines cleared you gain a level and gravity picks up: the pieces fall faster and faster, up to a frantic pace that tests your reflexes and your composure. The run ends when the stack reaches the top of the well and a new piece can no longer appear: your final score is everything you banked. To help you plan, a panel shows the next three pieces, a ghost projection shows where the active piece will land, and a hold slot lets you park an awkward piece for later. Every piece has its own neon colour and its own shape, finished with a dark outline, so they stay perfectly readable with colour blindness — the information never rests on colour alone. The controls work for touch as much as for the keyboard: on mobile, five large buttons sit under the well, in the thumb zone, to move, rotate, soft drop and slam the piece down; you can also swipe the well to move, tap to rotate and drag down to drop. On a computer, the arrows move and rotate, the down arrow speeds the descent and the spacebar fires the hard drop. It all runs at sixty frames per second, with a discreet synthesised cue on every move, rotation, lock and line clear. Néon Stack is free and instant in your browser, nothing to install, on desktop and mobile alike. Create an account to sync your high scores, enter the leaderboards and unlock trophies as you play.

Does Néon Stack work on mobile?

Yes. The game is responsive and fully playable with your fingers on phones and tablets, just like on desktop, with no app to install.

Why go for four lines at once instead of one at a time?

The scale is steeply progressive: four separate lines pay 400 points (4 × 100), while the same four cleared together — a QUAD — pay 800, all multiplied by your level. Taking the risk of stacking up for a QUAD doubles what you earn.

What is the hold slot actually for?

It lets you park the current piece and bring it back later. Ideal for storing a bar while you finish digging your well, or for shelving an awkward piece and pulling out the one you saved.
