What makes a circuit complete?
Rotate the tiles to connect the golden source to every scroll. All conduits must belong to a single connected network, and the final circuit must not leave open ends. A tile that looks connected locally can still prevent completion if another branch is isolated. Golden tiles cannot rotate, so treat them as fixed constraints rather than pieces you can change later.
How the 200 trials unlock
The first trial unlocks at zone 500. A further trial becomes available every 25 zones, up to the final unlock at zone 5,475. There are four groups of fifty fixed trials. Being strong enough to unlock a group does not mean its puzzles are already solved: complete the available trials in order to earn their rewards.
Solve the constraints before guessing
Begin at the border, the source and fixed golden tiles. A border limits the directions a conduit can face; a fixed tile limits the neighboring tiles. Follow one branch at a time, then inspect the entire network for disconnected sections and open ends. Later trials introduce additional mechanics explained in their help panel. Resetting a board lets you reconsider its layout without a timer or failure penalty.
Why a scroll bonus matters
Completed trials contribute to the Sanctuary scroll multiplier, which can reach ×200 and survives progression resets. Replaying a solved trial is not an unlimited source of additional multipliers. If bosses already die comfortably but scroll income feels slow, an unsolved Sanctuary trial may be a better next objective than a small increase to raw damage. Combine its permanent bonus with an appropriate equipment preset when evaluating boss rewards.
