100 Doors - Escape from Prison: how to start, control and improve
A practical 100 Doors - Escape from Prison guide covering the first steps, controls and one focused tip before you play.
Updated: November 7, 2026
Core mechanic
Inspect every prison cell, solve its clue and unlock door after door. Inspect each cell for numbers, tools and visual clues, solve its self-contained puzzle and use the result to unlock the next prison door. Items found in one part of a cell may need to be combined or applied elsewhere.
Controls and screen setup
Tap or click objects to inspect or collect them, drag usable items onto likely targets and enter codes through the on-screen puzzle controls.
How a run ends
The run usually fails when a move creates isolated gaps or removes the free space needed to rearrange later pieces.
Opening plan
Spend the first turns reading the full board, identify the non-reversible move and preserve at least one flexible route.
Common mistake
Do not solve only the most obvious local match; check what that move leaves behind for the following turn. Scan the room from edge to edge before guessing a code; small differences in repeated objects often reveal the intended order.
