Chaturaji and Chaturanga: Ancient Indian Chess Precursors

Chaturanga and Chaturaji are two of the earliest known chess-like board games, originating in India around the 6th-7th century AD (with possible roots tracing back further to the Gupta Empire or even the Indus Valley Civilization). Both games symbolize the four divisions of an ancient Indian army—infantry (pawns), cavalry (horses), elephants, and chariots—played on an ashtāpada (8x8 uncheckered board). Chaturanga is the foundational two-player strategy game widely regarded as the direct ancestor of modern chess, shatranj, xiangqi, shogi, and other variants. Chaturaji ("four kings") is a four-player adaptation, often incorporating elements of chance via dice, and was described as early as 1030 AD by Al-Biruni. While exact historical rules vary due to limited records and regional differences, reconstructions by historians like H.J.R. Murray provide a clear picture of their shared heritage and divergences.

Similarities

Both games share core mechanics that influenced global chess evolution:

Aspect Description
Board 8x8 uncheckered squares (ashtāpada), sometimes with markings unrelated to movement (possibly for dice variants).
Core Pieces Represent army units: pawns (forward 1, diagonal capture 1, no initial double-step); horse (knight: L-shape jump); chariot/boat (orthogonal any distance, non-jumping); king (adjacent any direction); elephant (limited leaper or slider).
No En Passant/Castling Absent in both; pawns promote under restrictions (e.g., to specific pieces if available).
Capture By landing on opponent's piece; jumping allowed for leapers (horse, elephant in some forms).
Cultural Role Pure skill (Chaturanga) or skill+luck (Chaturaji); spread via trade routes, evolving into international chess variants.

These overlaps make Chaturaji a direct extension of Chaturanga, with some sources even calling it "four-handed Chaturanga."

Differences

The games diverge significantly in scale, chance, and objectives, reflecting solo duels (Chaturanga) vs. multi-kingdom battles (Chaturaji).

Aspect Chaturanga (2-Player) Chaturaji (4-Player)
Players 2 (opposing sides; white first). 4 (clockwise turns; often teams, e.g., red+yellow vs. green+black opposites/partners).
Pieces per Player 16: 1 king (raja), 1 vizier (mantri: 1 diagonal), 2 elephants (2 diagonal leap), 2 horses, 2 chariots (rook), 8 pawns. 8: 1 king, 1 knight 1 pawn, 1 rook 1 bishop
Dice None (full player choice). none
Setup Offset kings (e.g., white e1, black d8); standard rows. Corner armies (back rank majors + pawn row); colors: green/red/yellow/black.
Winning Checkmate king or "bare king" (opponent left with only king); stalemate often wins for stalemated side. Points from captures (pawn=1, boat=3, king=3 knight 3 bishop 5) points can allow you to auto claim, you can also win the game by being the last one standing
Special Rules Raja cannot be left in check; promotion to vizier/chariot. Checking gives you points

Modern reconstructions (e.g., on Chess.com or Ludii) often simplify Chaturaji by omitting dice for strategy.

In essence, Chaturanga emphasizes tactical purity in a duel, while Chaturaji adds chaos because it has 4 players and sometimes dice. Though Chaturaji outlasted in some regions into the 20th century, both paved the way for chess's global dominance.

I noticed the only long-ranged piece in chaturanga was the rook, so the variant depends on shuffling a lot with lower rated games, but still, fun!

Was chaturaji actually from ancient India? I thought it was just some variant of chaturanga that later people made up and claimed it was the actual precursor to chess :/
