4×4 grids of votive candles with three states. The same pattern repeats in 15+ locations across the estate. What do they encode?
UnsolvedSetup: In the underground tombs, two votive candle stands display 4×4 grids. Each cell has one of three states: lit candle, unlit candle, or missing candle. The pattern near Clara Epsen's sarcophagus is nearly identical to one just outside the passage, differing only in blown-out candles.
The 4×4 pattern is everywhere: The same grid dimensions appear in the boiler room panels (×15), the boiler room elevator top, the attic box, the garage gas tank, the darkroom lower cabinet, the conservatory box, the pool dig spot, the tunnel to the sanctum doors, underpass hallway walls, throne room pillar bases, and more. Some have patterns, some are blank.
Three states: Unlike simple binary puzzles, the candles have three distinct values: missing (empty slot), unlit (candle present but dark), and lit (burning). This tri-state encoding could represent ternary data, or the missing candles may simply be structural.
No input found: Despite extensive searching, no 4×4 input mechanism has been discovered in-game. The trophy import screen in Blackbridge Grotto (a 2×8 = 16-cell display) is the closest match but has not been confirmed as related. Data mining has not revealed hidden triggers.
Alzara connection: The candles appear in one of Alzara's visions, but they cannot be interacted with during the vision sequence.
Two votive candle stands in the tombs display clear 4×4 grids. Each cell is either a lit candle, an unlit candle, or an empty slot. The pattern near Clara Epsen's sarcophagus is nearly identical to one just outside the passage, with only blown-out candles differing.
The same grid dimensions recur across the estate: boiler room panels (×15), boiler elevator, attic box, garage gas tank, darkroom cabinet, conservatory box, pool dig spot, tunnel to sanctum, underpass hallway, throne room pillars, freezer servers, classroom chairs, and more. Some have patterns, some are blank.
A candle stand that has been knocked over still shows a grid that lines up with the others, only with some candles missing, presumably because they fell out when it tipped. This suggests the pattern is deliberate, not decorative.
The tomb candles are shown in one of the Great Alzara's vision sequences. However, they cannot be interacted with during the vision, and Alzara doesn't directly reference them in dialogue.
Exhaustive searching and data mining have not revealed any 4×4 input grid in the game. The trophy import screen (2×8 = 16 cells) in Blackbridge Grotto is the closest match. The burning glass cannot be used to create 4×4 scorch marks anywhere meaningful.
One player noted that the top-left position is never filled in any of the known grid patterns. If unused cells represent 0, this could be significant for any encoding scheme. There also appear to be only 12 plates with space for a 13th.
The arches in the underpass hallway have rivets that could be read as 4 or 8-bit binary codes. The wall panels between arches are also 4×4 grids with some squares filled and others empty, matching the boiler room pattern.
Most classrooms arrange 16 chairs in a 4×4 grid. Some chairs have homework on them while most don't, creating a filled/empty pattern that mirrors the boiler room grids and candle stands.
The Blackbridge Grotto trophy import screen lets you select individual trophies in a 2×8 grid (= 16 cells). Why not just "import all"? The ability to pick individual trophies might serve as a hidden 16-bit input mechanism, but this is unconfirmed.
Letter number 7 in the mail room from Randolph includes a 4×4 grid showing security door levels. This is a known use of the 4×4 format within the game's lore, but may simply be utilitarian rather than puzzle-related.
A 4×4 grid appears at the treasure map dig spot in the pool. However, no noticeable patterns were found. It appears to be a generic filler texture rather than an encoded pattern, unlike the tomb candles.

The boiler room has 15 panels with identical 4×4 dimensions and similar on/off patterns. The tomb candles may be part of the same encoding system viewed from a different context. If the boiler panels are data, the candles could be a key, or vice versa. Solving one likely solves both.
Overlay all known 4×4 grids into one, summing each cell's value. With 3 states (missing=0, unlit=1, lit=2), the sums could map to alphabet positions (A=0, B=1, etc.). This approach requires a complete catalogue of all grids; the community may still be missing some. Early attempts were inconclusive.
Read each row as binary (lit=1, unlit=0, missing ignored or treated as 0). Each row encodes a value 0–15. Four rows per grid could spell out coordinates, letter pairs, or hex values. Alternatively, each full 4×4 grid is 16 bits encoding a single value 0–65535.
A 4×4 grid is a natural fit for a route cipher (text written in grid, read in a zig-zag path) or a modified 4×4 Polybius square. "Does it never end?" has 14 characters + 2 blanks = 16 cells. The phrase could be written into a grid and read via a specific route to produce a ciphertext.
Arranging four 4×4 grids together produces an 8×8 grid, a chessboard. Given the game's heavy chess and puzzle theming, this could encode a chess position, a move sequence, or map to the 8 ranks of the estate. Needs a verified arrangement of which grids connect.
The candle grids may be intentionally unsolvable in the current version. The Dirigiblocks update could introduce new rooms, mechanics, or input methods that give these patterns meaning. Several cut-content elements may be restored.
Some argue these are just environmental textures reused across the estate. The boiler room panels serve a mechanical function (heat indicators), and the tomb candles are simply atmospheric. However, the consistent 4×4 sizing and varied patterns make this unlikely for many players.
