Is Shogi Harder Than Chess? An Honest Answer

By the measures we can count, shogi is harder than chess: its game tree is vastly larger (about 10^226 possible games versus 10^123), its average position offers roughly 80 legal moves to chess’s 35, and drops mean complexity grows as the game continues. For a human learner, though, the answer has real nuance.

What “harder” even means

Two different questions hide inside this one, and they have different answers. Is shogi a deeper, more complex game than chess? Measurably yes. Is shogi harder for a person to learn and enjoy? Mostly no, with two honest caveats.

Getting this right matters, because the scary version (“hardest chess variant on Earth!”) stops people from trying a game whose basic rules take an hour. Let’s do the numbers first, then the human part.

The computable answer

Game researchers estimate complexity a few ways, and shogi outscales chess on all of them:

Branching factor. An average shogi position offers about 80 legal moves; an average chess position, about 35. The gap is mostly drops: every piece in hand multiplies your options across every empty square it could legally land on.

Game length. Average professional games run around 115 half-moves in shogi versus roughly 80 in chess. More moves, each chosen from more options.

Game-tree complexity. Compound those two and you get the standard estimates: around 10^226 possible shogi games against 10^123 for chess. The exponents are the point; that’s not “about twice as complex,” it’s a difference of a hundred orders of magnitude.

There’s also a structural quirk worth naming: chess simplifies as it goes (pieces leave, options shrink), so the hardest part of a chess game is the middle. Shogi accumulates: hands fill up, drop options multiply, and the endgame, with both kings under attack and pieces raining onto the board, is often the most complex phase. Computers felt this difference concretely; engines conquered shogi years after chess, with the top programs reaching and then passing professional level during the 2010s.

The human answer

Here’s where the honest nuance lives, because none of those numbers measure what a beginner experiences.

Learning the rules: about equal, maybe easier. Shogi has eight piece types to chess’s six, but most shogi pieces move one square in simple patterns, and there’s no castling procedure, no en passant, no pawn double-step. An hour with the rules covers everything.

The first fifty games: arguably friendlier than chess. This surprises people. In chess, a beginner who blunders a queen gets ground down over thirty hopeless moves; in shogi, blunders arm your comeback (every capture your opponent makes is a piece you might win back into your own hand). Beginners also aren’t punished by the complexity numbers, because both players face the same 80 options and neither is using most of them. Wide beats deep, at the start; more reasonable moves means more forgiveness for imperfect ones.

The two real barriers. First, the kanji: pieces are labeled in Japanese characters. Real hurdle, brief hurdle. There are only eight characters, recognition takes a few games (the pieces guide has a method), and our board offers symbol-based international pieces plus a toggle, so the alphabet never blocks the game. Second, thinner English resources: chess has a century of English books and a giant player pool; shogi’s literature is mostly Japanese. This gap is real and closing; it’s also, candidly, the gap this site was built to close.

Getting genuinely good: harder, and here the numbers return. Mastery means taming exactly what the metrics measure: reading forced sequences where drops multiply the tree, judging attacks where material can’t be counted the usual way, surviving endgames that get more complicated instead of less. Chess mastery leans on accumulated technique; shogi mastery leans on reading depth in a wider tree. Professionals train from childhood through institutionalized apprenticeship, and the consensus among strong players of both games is that shogi’s endgame is the single most calculation-heavy phase in either.

The verdict, with its nuance intact

Shogi is the deeper game by every formal measure, and reaching mastery is probably harder. Starting, however, is not: the rules are quick, early games are forgiving in ways chess never is, and the supposed barriers (kanji, resources) are days-sized problems, not years-sized ones.

So invert the question. If “harder” means “should I be intimidated,” no. If it means “will this game keep getting deeper for as long as I care to follow it,” yes, and that’s the strongest recommendation a strategy game can earn.

FAQ

Is shogi more complex than chess?

Yes, by standard measures. Shogi’s estimated game-tree complexity is about 10^226 versus chess’s 10^123, its average position offers roughly 80 legal moves versus 35, and games run longer. The drop rule drives the gap: pieces in hand multiply legal options throughout the game.

Is shogi hard for beginners to learn?

No. The rules take about an hour: most pieces move one square in simple patterns, and shogi has no castling, en passant, or double pawn moves to memorize. The kanji labels take a few games to recognize, and symbol-based international piece sets remove even that barrier for starting out.

Why did computers master chess before shogi?

Shogi’s larger search tree resisted the brute-force methods that cracked chess in the 1990s: more legal moves per position, longer games, and drops that keep complexity high into the endgame. Shogi engines reached and then surpassed top professional level during the 2010s.

Is the shogi endgame harder than the chess endgame?

They’re hard in opposite ways. Chess endgames are technical: precise play in simplified positions. Shogi endgames are combinational: both kings under simultaneous attack, pieces dropping from hand, victory decided by who mates first. Shogi’s endgame is widely considered the most calculation-intensive phase in either game.
