entropy

Entropy is not just a puzzle game — it is a beautifully crafted simulation inspired by thermodynamics.

In thermodynamics, Entropy (S) measures the number of possible arrangements of a system. A change in entropy is shown as ΔS. If the entropy of a system increases, ΔS is positive. If it decreases, ΔS is negative.

In this game, your goal is to bring a disordered system to its lowest entropy state: total illumination.

HOW IT WORKS

Each puzzle is a network of connected nodes. Tapping a node toggles its state and the state of all its neighbours. Find the perfect sequence to commission every node in the grid.

Simple concept. Infinite depth.

Recent changes:
Landscape play is much bigger — the board now uses the full
height of your screen.

All 4,000 levels now have names and descriptions, so you know
which boards fight back with tiles that flip on their own.

Achievement rewards are now claimed from the rewards screen,
so nothing gets missed.

World rank now counts campaign progress only.

Fixes: menus no longer get cut off on small or landscape
screens, and buttons are easier to tap.
