Samhain: The Veil Between is a free browser block puzzle built on the Celtic feast of Samhain, the old origin of Halloween. In the story, the Morrígan has loosed the Sluagh — the restless host of the dead — and the swan-maiden Caer Ibormeith is dissolving into wraiths. You are the last druid of Brú na Bóinne, setting carved standing stones to seal ley-lines and close the veil. Thirty chapters across four acts, plus an endless mode.
They are the two hazards. Grave-slabs rise out of the table from Act II onward: nothing can be built over them, and the only way to clear one is to seal its row or its column. From Act III onward, every few stones you set, a wraith slips through the veil and lands on an empty cell, where it blocks the same way. Both are swept away by any sealed line that crosses them.
| Thing | What it does | What it pays or costs |
|---|---|---|
| Stone cell placed | Fills one cell of the table | 2 points per cell |
| Sealed line | A full row or column is swept away | 100 points |
| Multi-seal | Several lines sealed by one stone | 50 points per extra line |
| Streak | Consecutive placements that seal | 20 points × streak |
| Veil perfect | The table is emptied in one seal | 500 points |
| Grave-slab | Blocks its cell from Act II on | Gone only when its line seals |
| Wraith | Lands every few stones from Act III on | Gone only when its line seals |
| Hint | Three per chapter, solver-proven | Free |
You score two points per stone cell placed, one hundred per sealed line, fifty for each extra line sealed at the same moment, and a streak bonus that grows with every consecutive placement that seals something. Emptying the whole table in one seal pays a five-hundred-point perfect bonus. Each chapter prints the reference score a strong solver achieved; three stars want eighty percent of it, two stars sixty-two percent, and one star is the chapter target.
| Act | Chapters | Where you are | What changes |
|---|---|---|---|
| I · The Hazel Woods | 1–8 | Samhain eve under the trees | The stones teach themselves; no hazards |
| II · The Mound of Hostages | 9–16 | The ancient burial mounds | Grave-slabs rise; only sealed lines remove them |
| III · The Plain of Wands | 17–24 | The bare plain the Sluagh ride | Wraiths land every few stones |
| IV · Brú na Bóinne | 25–30 | The great passage-mound at the Boyne | Graves and wraiths share the table |
Yes, and it is measured rather than promised. Every chapter runs on a fixed, seeded stone sequence — no random numbers while you play. During development a reference solver played every chapter with the same rules the player gets, its score was recorded as the par, and the win target was set to forty-five percent of that score. The same solver is shipped inside the game as the hint button, so the hint always offers a line that is actually on the board.
The Long Night. Waves of ever-larger targets with no chapter end: stones keep coming, the mix of shapes gets meaner, and from the third wave the Sluagh land wraiths on the table more and more often. Your best wave and score are kept in your own browser.
No download, no install, no account and no payment. The whole game is one HTML5 page: every stone, grave, wraith and sound is drawn or synthesised in the browser. Drag-and-drop works with a mouse and tap-to-place works with a thumb, and it runs down to a 320-pixel screen in portrait or landscape. Progress and stars are stored in your own browser and nothing is uploaded.
Everything is generated: no image is loaded by the game, no audio file is played, no third-party script runs. The stones, the table, the moon and the mist are Canvas 2D drawn from the same level data the reference solver reads, and the drone, the harp plucks, the stone clacks and the seal chimes are synthesised with the Web Audio API. The rules contain no random numbers — every stone comes from a seeded sequence, so a chapter plays identically on every device. Progress and stars live in your own browser under samhain.veil.v1. Nothing is uploaded, because there is no server.

Drag one of the three offered stones onto the eight-by-eight table, or tap the stone and then tap a glowing cell. Stones never rotate. When every cell of a full row or a full column holds stone, the line seals and all of it is swept away for points. The chapter is won when your score reaches the target line; it is lost when none of the three offered stones can fit anywhere.
