Thornwood Tactics: How to Win Across Four Seasons | Playgridia

2026-08-10

If you already know how Thornwood works, this is the article about winning it. Three actions a turn, four verbs, one owner per clearing, a harvest at the end of every season — that part is easy. What is not obvious is where the points actually come from, which numbers decide a raid before you press Confirm, and why a bigger army keeps losing to a smaller one that planted earlier.

The recap, and then no more rules: a turn is three actions drawn from MUSTER, MARCH, RAID and ROOT. Every clearing has exactly one owner and one printed bounty. At the end of each of the four seasons there is a harvest — every clearing you hold pays its bounty, your clan bonus is added, and the autumn harvest pays double. After the winter harvest, the highest score wins.

Count your turns before you spend them

At three or four players a season is three rounds, so the whole match is twelve rounds: twelve turns each, thirty-six action points. At two players a season is four rounds — sixteen turns. The quick match-length option takes one round off every season. That number is the most useful thing you can hold in your head, because it turns every plan into a budget. An action spent in round two has four harvests in front of it; the same action in round eleven has one.

The banner always tells you the season and how many rounds are left until the harvest, and that sentence is a spending instruction. Early rounds are for investing. Late rounds are for taking ground and standing on it.

A Root planted in spring is worth six points; the same Root in winter is worth two

ROOT scores 1 point the moment you plant it and raises that clearing's bounty by 1 permanently. A Root planted before the spring harvest therefore pays 1 at spring, 1 at summer, 2 at autumn and 1 at winter: six points for one action. Plant the same Root in winter and it pays two. Nothing else in the game compounds like that, which is why a strong opening is Root-heavy and a strong endgame is not.

Where matters as much as when. A clearing holds as many Roots as its printed bounty, so a bounty-3 glade can carry three of them and finish the match paying six a harvest, while your bounty-1 home is full after one. And a Root is also a muster point: without one, the only place you can raise warriors is your own home, and every warrior raised there needs a MARCH — a second action — to reach a front. One Root on a forward clearing turns a two-action walk into a one-action arrival.

How many attackers you need is set by their warriors; how many you lose is set by their power

This is the piece most players have backwards. Each side loses half the other side's power, rounded up, capped at what that side has standing. Two consequences follow:

• To take a clearing you must remove every defending warrior, and in a neutral season that means committing roughly twice as many warriors as are standing there. Four attackers reliably clear two defenders; six clear three. Summer gives the attacker +1, so summer costs you one fewer.
• Roots, winter and a defender's clan bonus do not raise that number — they raise your bill. Three warriors in open wild ground and three warriors behind two Roots in winter both need about six attackers. The difference is that you lose two in the first case and four in the second, and you still need somebody left standing to walk in.

So developed ground is not harder to take, it is more expensive to take — and the second-order effect is what decides matches. An army spent grinding down a dug-in clearing is an army that is not on the board when the harvest bell rings.

Read the thorn deck before you commit

The thorn deck is twelve cards — four +1, four 0, four −1 — drawn without replacement, both sides face up, and what is left is printed beside the raid. That is the entire randomness of the game, and it is countable, so treat it that way.

Plan against the worst row on the confirm bar, never the likely one. A raid that only captures on the average draw is a raid that throws your army away often enough to lose you the season. And when the remaining +1s are gone, every attacker's ceiling has dropped — that is a window to sit on what you hold, and the reshuffle is the window to move again. Reading those two numbers costs nothing and is the highest-value habit in the game.

Open on wild ground, because the guards tell you the price

Every unowned clearing is garrisoned by its own bounty: a bounty-3 glade is defended by three, a bounty-1 corner by one. Wild defenders get the season bonus and any Roots, but never a clan bonus, so they are the cheapest ground on the board — and the only ground where misreading a fight costs you nothing but soldiers.

You start with three warriors on a bounty-1 home that can never be raided and is never worth sitting on. A strong first season is: muster, take the cheap wild ground beside you, and Root the first clearing worth more than 1 that you can genuinely hold. Raiding a rival in spring is almost always worse than raiding the wood — the same action at worse odds, and it paints a target on you three seasons before it has to be there. Casualties return to your supply of eighteen and can be mustered again, so losing warriors costs tempo. Losing position costs tempo and points.

Your clan bonus caps at three, so go and get exactly three

All four clans play the same four verbs and then add one signature and one harvest bonus, and that bonus is capped at 3. The cap is a target, not a ceiling to chase past:

• Ironclaw musters 3 instead of 2 (four in spring) and scores its fullest clearing — but three warriors in one clearing already maxes the bonus. Stacking nine buys defence, not points.
• Skyplume musters anywhere it holds, gets one free MUSTER a turn, and marches two paths through its own ground. Its bonus is terrain variety, and there are exactly three terrains, so one Marsh, one Grove and one Ridge maxes it. Chase the type you are missing, never more of what you own.
• Thistle gets one free ROOT a turn and +1 defending, and scores clearings that touch a rival. Turtling into a quiet corner scores it zero: it wants three contested borders and the Roots to keep them.
• Mistmane gets one free RAID a turn and scores clearings taken this season — and that counter resets at every season boundary. Three captures in autumn are worth six points; three captures spread across two seasons are worth three and three.

Three of the four clans get a free verb, which is a fourth action every single turn. Ending a turn without spending it throws away a quarter of your turn, all match long.

A capture keeps the Roots, so the leader is the board's best target

A capture pays 2 points immediately, and everything the loser had dug in transfers with the ground. That is deliberately the catch-up mechanism — there is no rubber band here, there is a map — and it changes what both sides should be doing. If you are behind, attack the biggest score rather than the nearest clearing. If you are ahead, your developed clearings need garrisons more than they need another Root, and being the second-richest player until the last round of autumn is a perfectly good plan.

Because a harvest only counts what you hold when the bell rings, a clearing captured on the final turn before a harvest pays exactly as much as one held all season, and a clearing lost on that turn pays nothing at all. Time your raids to land in the last round of a season, and above all in the last round of autumn, which is the double one. Holding a rich glade for two rounds and losing it on the third is the most common way to score nothing with a good army. Watch the gap too: the match ends early once second place can no longer catch up.

Three boards, three different games

Fernvale, the default, is twelve clearings worth 22 bounty in total, and its two bounty-3 glades sit on opposite flanks with no path between them. You have to commit to one — an army parked in the middle threatens neither.

Winterhold puts half the board's bounty into four bounty-3 clearings in the inner ring, tied together by 24 paths. There is no quiet corner to farm and nothing is more than two marches from any fight, so raw warrior count matters more here than clever position.

Lakeland is a ring around an impassable lake with only two fords, and all four bounty-3 clearings are the ford-heads. Most clearings have exactly two neighbours, so a single stack corks a flank and an army that walks the wrong way round the water loses several turns finding out. It is the board where MARCH is genuinely worth an action.
