Photosynthesis Board Game Review
Photosynthesis, designed by Hjalmar Hach and published by Blue Orange Games in 2017, is a competitive abstract strategy game about growing trees in a shared forest. Players guide their species through a full life cycle — seed to small tree to towering canopy — while a 3D sun rotates around a hexagonal board, casting shadows that block opponents from earning light points. It plays 2–4 players, ages 8 and up, in roughly 30–60 minutes. This review covers what you get in the box, how the game plays, and who it works best for.
Photosynthesis Overview
The theme is simple: you are a species of tree competing for sunlight. Your goal is to plant seeds, grow them into tall trees, then harvest those large trees for scoring tokens. Trees closer to the center of the board score more points when harvested. The catch? A rotating sun determines which trees collect light points each round, and taller trees cast shadows that block shorter ones behind them.
The result is a game that looks peaceful — a table covered in colourful cardboard trees — but plays with real bite. Blocking an opponent’s tree from sunlight at the right moment can cripple their economy for several rounds.

What’s in the Photosynthesis Box
The standout feature is the 3D cardboard trees. Each of the four player colours gets a full set of seeds, small trees, medium trees, and large trees that physically stand on the board. When a game is in progress, the table looks like a miniature forest — it’s one of the most visually striking setups of any strategy board game at this price point.

The cardboard trees are sturdy and pop out of their punch boards cleanly. The player boards are well-designed, with pictorial references for every action cost printed directly on the board — no separate reference cards needed. The sun segment is functional but a bit fiddly to reposition each round. Storage inside the box is basic: four cardboard dividers separate the player sets, but there’s no custom insert.
Photosynthesis Pros and Cons
- The sun/shadow mechanic is genuinely original. Nothing else on the market works quite like it.
- Theme and mechanics fit together almost perfectly. Growing trees, collecting sunlight, and casting shadows all make intuitive sense.
- The 3D tree display grabs attention and makes Photosynthesis an easy sell to new players.
- Rules are short — about three pages — and can be taught in 10–15 minutes.
- Good tension between growing your engine (keeping big trees for income) and scoring points (harvesting those same trees).
- Won the Mensa Select award in 2018, confirming accessibility with real strategic depth.
- Replay value is limited since all four tree species are mechanically identical. No asymmetry between players.
- Prone to analysis paralysis. Players who want to optimise every move can slow the game down well past the advertised 60 minutes.
- The sun segment is slightly annoying to move and reposition every round.
- At two players, the board feels spacious and the game loses some of its competitive edge.
- Scoring can feel opaque on your first play. New players often don’t realise how important central board positions are until it’s too late.
How to Play Photosynthesis
Setup
Place the hexagonal board in the centre of the table. Each player picks a colour and takes the matching player board with all their seeds and trees. Stack the scoring tokens by soil type (leaf count) on the board in descending order, highest value on top. Place the sun segment on the sun symbol, and set the three revolution counters at the edge of the board. In a two-player game, remove the darkest green scoring tokens from the four-leaf stack.
Players then take turns placing one small tree each on the outer ring of the board, going around twice so everyone starts with two small trees.
Round Structure
Each round has two phases. First, the Photosynthesis Phase: the first player moves the sun segment one position clockwise, and all players collect light points based on which of their trees are in direct sunlight. Small trees earn one light point, medium trees earn two, and large trees earn three. Trees in the shadow of an equal-sized or larger tree earn nothing.
Second, the Life Cycle Phase: starting with the first player, each person spends light points to take actions. You can buy seeds or trees from your player board, plant a seed adjacent to one of your trees, grow an existing seed or tree to the next size, or harvest a large tree to collect a scoring token. Each action has a light point cost printed on your player board.
Winning Photosynthesis
The game ends after the sun completes three full revolutions around the board (18 rounds total). Players add up their scoring tokens, plus one bonus point for every three unspent light points. Highest total wins. Ties go to the player with more seeds and trees still on the board.
An advanced variant adds a fourth sun revolution and restricts planting or growing in shadowed spaces, which makes the game tighter and more punishing.

Local stock for Photosynthesis tends to be spotty in India. If you see it at Boardway India or Bored Game Company near the ₹3,000–5,000 range, that’s a fair deal. Amazon.in listings above ₹10,000 are typically fulfilled by overseas sellers and include steep import fees — not worth it when specialty shops restock regularly.
Photosynthesis Game Mechanics
Photosynthesis runs on an action point system. Light points are both your currency and your score multiplier — every point you spend growing a tree is a point you can’t bank at the end of the game. This creates a constant push and pull between investing in your board position and cashing out for victory points.
The sun rotation is what makes the whole thing tick. Because the sun moves to six positions around the board, a tree that earns three light points now might earn zero on the next turn if a taller tree shifts into alignment. You have to plan several rounds ahead, predicting not just where the sun will be but what your opponents will grow and where. It’s closer to abstract strategy than it first appears.
Shadow casting adds an area control layer. A large tree casts a shadow three spaces long, a medium tree two spaces, and a small tree one space. Only trees of equal or smaller size get blocked. This means growing a tree tall isn’t just good for income — it’s a weapon against neighbouring opponents. The interaction between the income system, the shadow mechanic, and the scoring token depletion (top tokens are worth more, so harvesting early pays better) gives Photosynthesis a satisfying arc from open exploration to tight, contested end-game decisions.
Who Should Play Photosynthesis
Photosynthesis fits best with groups of three or four players who like mid-weight strategy games and don’t mind direct competition disguised as something serene. If your group enjoys Blokus or Azul — games where spatial awareness and blocking matter — this scratches a similar itch with more depth and a longer arc.
It works well as a gateway-plus game. The rules are simple enough for families with kids around age 10 (the 8+ rating is optimistic for grasping strategy), and the visual appeal makes it easy to get people to the table. Experienced gamers will appreciate the decision space, though they may tire of the lack of asymmetry after ten or fifteen plays.
At two players, the board opens up and the game becomes more of a puzzle and less of a fight. Some people prefer this calmer feel, but most reviewers agree that three or four is the sweet spot. If you play a lot of family board games and want something with sharper teeth, Photosynthesis delivers.
Skip it if your group dislikes games where opponents can directly block your progress, or if analysis paralysis is a regular problem at your table.
FAQ
Is Photosynthesis good for beginners?
The rules are short and the action costs are printed on each player board, so it’s easy to learn. Real strategic understanding takes a game or two to develop, though. Beginners will make costly mistakes early on, like ignoring the centre of the board, but that’s part of the learning curve.
How long does Photosynthesis take to play?
Experienced groups finish in 30–45 minutes. First games with new players can stretch past an hour, especially at four players. The advanced variant with a fourth sun revolution adds another 15–20 minutes.
What’s the best player count for Photosynthesis?
Three or four players. At these counts, the board fills up fast and the shadow-blocking becomes a real factor. Two players is more relaxed and puzzle-like, which some enjoy but others find too open.
Is the Photosynthesis: Under the Moonlight expansion worth it?
The 2020 expansion adds a moon mechanic and forest animals with special abilities. It doesn’t change the base game much, but the animal powers introduce some variety that the original lacks. It’s a solid pickup if you’ve played the base game a dozen times and want more to think about.
What games are similar to Photosynthesis?
Azul shares the accessible-but-competitive feel with a spatial element. Reef is another abstract game about building up structures for points. For something heavier with a nature theme, consider Wingspan or Everdell. None of these have the sun/shadow mechanic, though — that’s unique to Photosynthesis.
