New · the six-sided board

Star Battle, on a hex board.

The same game you know, with one twist that changes everything: a hexagon has six neighbours and three line directions. Rows, ↘ diagonals and ↙ diagonals all take stars, so every count you are used to now runs three ways. Twenty boards are free.

The rules, in one minute

A hex board is split into regions, just like the square game. Place stars so that every unit holds exactly the number the board asks for, and no two stars touch.

  • Every row holds the stars. Rows run left to right, as always.
  • Every ↘ diagonal holds the stars. On a hex board this is a line, not a corner-to-corner guess.
  • Every ↙ diagonal holds the stars. The third direction, and the one that trips new players.
  • Every region holds the stars. Regions are the tinted shapes.
  • No two stars touch. A hex cell has six neighbours, not eight, so a star blocks a little less than it does on a square board.

One star or two. Most hex boards ask for one star per unit. The two-star packs ask for two, and the counting gets a lot richer.

Three sizes, seven packs

Boards come in three sizes: a side of four (37 cells), five (61 cells) or six (91 cells). Every board is generated with a unique solution and solved by the engine before it is served, so nothing needs a guess.

The same engine, the same review

Hex is not a side mode. It runs on the same machinery as the square game, ported rung by rung.

A hint that teaches.Every hint names the unit that breaks and walks its reasoning step by step, with the regions it names lit on the board. Relays show the star they force; counts show the zones they count.
A review of every solve.After you finish, your solve is replayed move by move: the brilliancies, the slips, and the easier line you missed.
Graded before you start.Each board carries its difficulty chart, its hardest technique and an estimated solve time, all read off the puzzle itself.

Questions

Is it harder than the square game?
Not by rule, but it reads differently. Three line families cross every cell, so the counts you are used to run along diagonals too. Most players find the first few boards disorienting and then it clicks. The free pack starts gentle.
Where are the columns?
There are none. A hex grid has no vertical line of cells that share edges, so the three units are rows and the two diagonals. The board labels each ↘ diagonal with a letter and each row with a number, so a cell is still "D5".
Do I need an account?
No. The free pack plays with no sign-up. An account only saves progress across devices and carries the unlock.
Is there a tutorial?
Yes. The first time you open a hex board the app shows the short delta lesson, then a guided first solve. You can replay it any time from Settings.

Six sides. Three directions. Twenty free boards.
