Forty campaign boards, from guided tutorials to a harder 6x6 endgame.

Chapter 1

Foundations

Three tutorials plus seven tighter 5x5 boards that make overlap reasoning show up earlier.

TUTORIAL 01

Tutorial 1: One sum, one answer

A single hidden cell introduces the core meaning of clue totals.

Par time: 25sIn progress
Open board

TUTORIAL 02

Tutorial 2: Two cells, one total

The board shows how a clue total can split across more than one hidden value.

TUTORIAL 03

Tutorial 3: Read the overlap

Use intersecting clue regions to fix the middle cell before the edges.

LEVEL 004

Level 4: First brace

An early 5x5 board that starts leaning on overlaps instead of direct singles.

Par time: 97sLocked
Locked

LEVEL 005

Level 5: Side pocket

A small side cluster opens the rest of the board once the outer lane is read correctly.

Par time: 99sLocked
Locked

LEVEL 006

Level 6: Narrow lane

The middle row begins to demand cleaner comparisons between similar local sums.

Par time: 105sLocked

LEVEL 007

Level 7: Crossing shelf

Two crossing runs of hidden cells create the first real chain of eliminations.

Par time: 107sLocked
Locked

LEVEL 008

Level 8: Dense corner

A heavier top-left pocket makes the board feel less open and more deliberate.

Par time: 111sLocked
Locked

LEVEL 009

Level 9: Quiet hinge

Work through a sparse hinge first, then use it to unlock the denser half.

Par time: 114sLocked
Locked

LEVEL 010

Level 10: Warm stack

The early campaign closes with a tighter 5x5 that rewards clean sequencing.

Par time: 121sLocked
Locked

Chapter 2

Combinations

The campaign widens from late 5x5 boards into the first demanding 6x6 layouts.

LEVEL 011

Level 11: Center knot

A compact knot through the middle asks for steadier cross-checking than the first chapter.

Par time: 124sLocked
Locked

LEVEL 012

Level 12: Short weave

Small weave patterns keep feeding each other until the edge answers settle.

Par time: 132sLocked
Locked

LEVEL 013

Level 13: Wide hinge

The first 6x6 board widens the field without giving back much clarity.

Par time: 172sLocked
Locked

LEVEL 014

Level 14: Split basin

Separated basins of information only meet once the middle clues are compared carefully.

Par time: 175sLocked
Locked

LEVEL 015

Level 15: Cross current

Two strong currents run against each other and force more committed deductions.

Par time: 180sLocked
Locked

LEVEL 016

Level 16: Long diagonal

Diagonal pressure starts to matter more than obvious row or column reads.

Par time: 184sLocked
Locked

LEVEL 017

Level 17: Twin pockets

Paired pockets look independent at first, then collapse together under shared totals.

Par time: 191sLocked
Locked

LEVEL 018

Level 18: Narrow bridge

A thin bridge connects the board and turns local certainty into global progress.

Par time: 193sLocked
Locked

LEVEL 019

Level 19: Open ridge

A broad ridge of clue totals holds the board together while lower branches stay slippery.

Par time: 197sLocked
Locked

LEVEL 020

Level 20: Broken belt

A broken band across the board creates longer elimination chains with fewer freebies.

Par time: 204sLocked
Locked

Chapter 3

Interlock

Dense 6x6 boards with repeated totals, longer chains, and fewer direct placements.

LEVEL 021

Level 21: Deep middle

The middle third becomes dense enough that small mistakes echo through multiple regions.

Par time: 214sLocked
Locked

LEVEL 022

Level 22: Heavy ladder

You climb this board rung by rung, with each solved step tightening the next.

Par time: 218sLocked
Locked

LEVEL 023

Level 23: Offset seam

Offset seams make repeated totals harder to separate unless the whole board is tracked.

Par time: 223sLocked
Locked

LEVEL 024

Level 24: Dense orbit

A packed orbit of hidden cells keeps feeding information back into itself.

Par time: 231sLocked
Locked

LEVEL 025

Level 25: Double trench

Two trenches cut through the board and demand cleaner sequencing than raw guessing ever could.

Par time: 236sLocked
Locked

LEVEL 026

Level 26: Iron hinge

One rigid hinge stabilizes the board, but only after several ambiguous groups are untangled.

Par time: 243sLocked
Locked

LEVEL 027

Level 27: Long shoulder

A long outer shoulder keeps the solution stretched across multiple slow deductions.

Par time: 249sLocked
Locked

LEVEL 028

Level 28: Braided ring

Several braided loops feed the same totals and force patient elimination.

Par time: 257sLocked
Locked

LEVEL 029

Level 29: Folded arc

The board folds back on itself, making it easier to misread repeated clue shapes.

Par time: 268sLocked
Locked

LEVEL 030

Level 30: Inner wall

A hard inner wall blocks progress until a few precise openings are found.

Par time: 273sLocked

Chapter 4

Endgame

A hard tail of tightly coupled boards that sustain pressure deep into the solve.

LEVEL 031

Level 31: Cold span

The endgame starts with a colder board that gives very little away for free.

Par time: 281sLocked
Locked

LEVEL 032

Level 32: Mirror strain

Mirrored-looking totals create pressure because the wrong interpretation stays plausible for too long.

Par time: 291sLocked

LEVEL 033

Level 33: Late pressure

The board stays tense even after the first breakthroughs, with little cleanup at the end.

Par time: 297sLocked

LEVEL 034

Level 34: Locked tide

Large clue tides move together and punish shallow local reading.

Par time: 305sLocked
Locked

LEVEL 035

Level 35: Black lattice

A dark lattice of shared cells turns nearly every answer into a dependency.

Par time: 318sLocked
Locked

LEVEL 036

Level 36: Deep vault

A deeper vault of overlapping sums makes each safe placement feel earned.

Par time: 330sLocked

LEVEL 040

Level 40: Summit grid
