Logic Puzzle Library

Dot Connect, Bridges & more

Pencil-and-paper logic, one shelf. Start with a relaxing line puzzle, then move on to boards that read like small proofs: lights that may not see each other, diagonals that must never close a loop, bridges that count, a fleet hidden by its numbers. Logic puzzles, all in one app - no account, no sign-in, and every game works offline.

DOT CONNECT - NUMBERLINK

Draw a path between each pair of matching dots and cover every cell on the board. Redraw a color as often as you like - the old path is erased, never penalised.

LIGHT UP - AKARI

Tap a cell and a light shines up, down, left and right until a wall stops it. Light every dark cell, but never let two lights see each other. Numbered walls say how many lights touch them.

SLANT

Every square takes one diagonal. The numbers sit on the dots and count the diagonals that touch them, and the lines may never close a loop. Tap a square to flip its line.

HASHI - BRIDGES

Each island shows how many bridges must reach it. Drag from island to island, never cross two bridges, and finish with every island joined into one network.

BIMARU FLEET LOGIC

A fleet is hidden in the grid. The numbers on the edges count the ship squares in each row and column, and ships never touch - not even at the corners.

WHAT CHANGED

Dot Connect has grown into a collection. One coin balance now covers every game, and the daily bonus comes once a day for the whole app. Your Dot Connect progress and coins carry over.
