Overview

Riddler has hidden away some big surprises and privileged conversations behind his network of collectibles. Every Riddler trophy you collect, puzzle you complete, and riddle you solve unlocks one spot on one of these Grids. Destructibles (Militia Shields, Insect Crates, Jack in the Boxes, and Spider Drones) also go toward clearing every space on the Grids. Completing a Grid unlocks an exclusive audio tape, playable once unlocked from certain Bio pages.

Grids for the three main islands have 18 fields each, and are completed with 17 Riddler challenges solved and five Destructibles smashed. Grids for smaller interiors have nine spaces, requiring eight completed Riddler challenges and five Destructibles demolished. If you’re on your way to completing a Grid and unlocking an audio tape, cross-reference with the Riddler Collectibles chapter to track down anything you need.
