Foldfall

Beta 1.0.1

One fold. Two players.

Foldfall is a block battle for two on one device. Unfold your phone, lay it flat on the table, and each player takes a half. Clear lines and throw blocks through the gap in the hinge so they rain down on your opponent.

How to play.

TapRotate the block.
DragMove the block left or right.
Towards youDrop the block.
Towards the hingeThrow. Hit the gap and it lands on your opponent's pile. Hit the wall and it falls back on you. The gap starts wide and narrows over time.

What it looks like.

Two boards meeting at the hinge, a blue block flying through the gap in the wall — One board across the fold. The wall with the gap sits right in the middle, menu and scores at the edges.

Foldfall start screen with title, game modes and settings — The start screen: jump in on the left, set difficulty, fold angle and sound on the right.

Four intro cards: lay it flat, control your block, throw through the hinge, clear your field — On first launch, a short intro explains the game in four cards.

Two ways to play.

Two players

You both start with the same pile. First to clear their pile wins. First to hit the top loses.

Solo vs. AI

A race against the AI on the clock: can you set a best time? Stand the foldable up like a laptop. The steeper the fold, the narrower the gap and the more points each line is worth.

Three levels

Easy, medium, hard: a taller starting pile and a faster pace. Best scores stay on your device.

Made for foldables. Plays everywhere.

Foldfall is at its best on an unfolded foldable, because the hinge is part of the board. On regular Android phones and tablets the app splits the screen down the middle, so you play without a real fold. An iPhone and iPad version is in the works.

Install in three steps.

On your Android device, tap “Download the beta”.
Open the file. Android asks whether your browser may install apps: allow it once.
Tap “Install”. If Play Protect warns because the app is not from the Play Store, choose “Install anyway”.

↓ Download the beta

Foldfall isn't on the Play Store yet. The beta is signed with the key of HMZ craftsmanship GmbH, so later versions install right over it.

The beta runs until November 10, 2026. After that, grab the next version here and install it right over the old one.
