Circuit
Count

A logic puzzle where you choose only the needed connections from many candidate lines to satisfy numbered nodes.

Circuit Count

Overview

Circuit Count is a logic puzzle where each node must end with exactly the number of selected lines shown on it. Lines can be freely toggled, so you narrow the board down by comparing dense candidates, diagonal lines, and each node’s remaining count. Level 1 focuses on the number rule, then later stages add more candidate lines.

How to play

01

Match the numbers

Each node number is the final number of connected lines it needs.

Early Level 1 stages use almost only forced moves so the number rule is clear.
02

Select lines

Select candidate lines to connect them. Select again to remove them.

Clear the stage when every node has exactly its required number of lines.
03

Compare candidates

Later stages add diagonal and longer candidate lines. Keep only the connections that match the numbers.

Selected lines can always be removed. Adjust while watching each node’s current count.
04

Time attack

Compete by clear time. Extra toggles add time.

There is no terminal failure. Remove wrong lines and rebuild the circuit.

Difficulty

99 stages total. Every 11 stages, the level increases.

Abilities you'll build

Processing speed

Spotting forced lines quickly and reducing extra toggles trains processing speed.

Working memory

Holding each node’s remaining count and candidate lines in mind trains working memory.

Reasoning

Narrowing valid connections from number constraints and candidate lines trains logical reasoning.

Self-control

Re-selecting the needed lines from a growing candidate set trains decision control.
