In this game, you can…

• …solve every puzzle by deduction without ever needing to guess.
• …use bracket and dash symbols that tell you whether blue cells in a line must be consecutive or separated.
• …click a number outside the grid to strike through an entire row once you've ruled it out, changing how you work the board.

In this game, you can…

• …solve every hex-grid board with pure logic and never have to guess.
• …use blue number tiles that count how many blue cells sit within a radius, including other radius-clue tiles.
• …hit question-mark tiles that hide information and split the board into sections, forcing you to narrow down huge uncertain areas.

In this game, you can…

• …reroute connections by rotating nodes and flipping junctions so the signal reaches only the hooks you want to pull.
• …watch solved wiring and nodes vanish on their own, leaving the remaining puzzle cleaner as you go.
• …stack switches, gates, remote triggers, and wireless jumps into a dense little logic machine you have to fire in the right order.

In this game, you can…

• …enter an eight-digit seed, generate a new board instantly, and share that exact puzzle with friends.
• …build your own puzzle in an editor and have an auto-solver verify it's solvable with zero guessing.
• …use edge numbers and special symbols to prove which tiles are mines without guessing.
