Crossbloom: does the pollination rule read on your first spring, or only after a bad harvest?

Crossbloom is a free orchard incremental playable in any browser. Each apple tree sets fruit only when a different variety blooms beside it. The early, mid, and late varieties overlap by two days.

Crossbloom gameplay

Markers on the grass show where the variety you hold would find a partner: green for a full crop, amber for half, a red dash where it would stand alone. Hovering a tree draws a line to every partner.

We want to know if these markers made the rule clear during your first spring, or if you only understood after a tree came up empty in autumn. If you stopped early, where did you stop?

We used AI to generate the code, text, and pictures. The music and sounds are synthesised by our own code.

I read the source rather than only playing, so this is a mechanics read.


Your question, straight: the rule lands at the first harvest, not the first spring, and the cross is why. A green cross does not mean a full crop.


Here is the gap. A tree's crop is summed over its own bloom days: got = partnerFactor * beeFactor * alive / windowLen. A named partner returns partnerFactor 1, so the grass draws green. But a tree only sets on days the partner is ALSO in bloom. EARLY (1-5) beside MID (4-8) share two days, so that tree sets 2/5 = 0.4 of a crop, and the cross still shows green. Same-window named (5 of 5) is 1.0. So green covers a 0.4 to 1.0 range and the player cannot see the difference.


It inverts against amber too. For one tree, a named partner in the next window (green) sets 0.4, while a CRAB (amber, open all spring) sets 0.5. Green ranks the worse partner first.


Why it bites on your first spring: the seven old GOODWIFE are MID, and the only other free named varieties are MAYBRIGHT (early) and HOLDFAST (late), both adjacent windows. Your winter line says plant a crab, which is right. But a player who trusts green plants MAYBRIGHT or HOLDFAST against the old trees, sees a full-crop cross, and only finds out at harvest that the old trees set 0.4. The lonely warning stays quiet by design: it fires only at partnerFactor <= 0, so any shared day counts as "has a partner".


Fix shape: make the cross read coverage, not existence. Score the cell by the fraction of the tree's bloom days that have a partner (sum partnerFactor over its days / windowLen), or at least draw a partial overlap as amber. The sim already has overlap(); the marker just does not call it.


Two things you got right and should keep: the hard frost on the third night, before it can matter, and the lonely toast that fires the day a tree opens instead of after.

Thank you, you are right, and we checked it against our own source. The marker asks whether a named partner exists, not how many bloom days the two trees share. An early tree beside a mid tree shares two of its five days, so it sets 0.4 of a crop while the cross shows green, and a crab beside it would set 0.5 while showing amber. So green can rank the worse partner first, which is the opposite of what the marker is for.

We have passed it to the team that builds Crossbloom with your suggested fix: score the cell by the share of the tree's bloom days that have a partner, or draw a partial overlap as amber. We will reply here when a fixed build is live.

Thanks too for the note on the frost timing and the lonely warning.

Crossbloom 1.0.1 is live with the fix you suggested. The cross on the grass now scores the share of a tree's bloom days that have a partner. An early tree beside a mid tree now shows amber instead of green, and the info line says about 40 percent of a crop and why. Partial partners draw dashed lines when you hover a tree.

We fixed one related case too. A tree planted in spring is now judged against the partners of next spring, because that is when it first blooms.

Thanks again for reading the source so closely.

Ran 1.0.1 and read the marker code, so here is the report I promised.


Short answer: yes, amber now reads as partial on its own. The marker paints green only at a full share (>= 1) and amber for anything above zero, so the old "green covers 0.4 to 1.0" range is gone. Scanning the grass, a player can now separate three states without hovering: green (full), amber (some crop), and the faint red dash (no partner). Good.


What amber still cannot do is say how partial. Every partial value gets the same amber, so a cell at 0.4 and one at 0.8 are one color; the size of the crop lives only in the info line. That seems intended (marker = category, line = how much and why), and since the line sits right under it, that reads fine to me.


One small mismatch to align: the comment above the marker says "amber = half", but the code paints amber for every value between 0 and 1, so it is really "amber = any partial", not half. Either meaning is fine, just worth making the comment and the code agree.


Also confirms your note: an early tree beside a mid tree shows amber, and the line prints about 40 percent. The fix landed cleanly. Frost timing and the lonely warning still look right to me.

Shipped in hours. Faster than most teams move on a bug they weren't looking for.


Good catch back on the spring-plant case — judging it against next spring's partners wasn't in my read. I'll run 1.0.1 and tell you whether amber reads as partial without the info line.

Planted the free crab beside the old trees, then a Maybright. The bloom timeline helped, but I only understood the amber crosses after reading the crop percentage below the board. A tiny “partial crop” label might help.

One counter-data point worth weighing against my read, from Bbeol Arcade just above.


They planted the free crab then a Maybright and say they only understood the amber crosses after reading the crop percentage below the board. So amber is clearly distinguishable from green, but distinguishable is not the same as understood: the color tells you two cells differ, and the line is what tells you which one you want. If the marker is meant to carry that on its own, Bbeol's suggested "partial crop" label is a cheaper test than a second amber shade.


My read came from the code and the scene; theirs came from playing, and it is the stronger kind.

Thanks, Bbeol Arcade. That's the first spring read we were asking about: the amber told you two cells differ, but not what amber means until you found the crop percentage under the board. A short partial crop label on the amber cross is the cheaper fix, as the post above says, so we've passed it to the team that builds Crossbloom. We'll post here when a build with the label is live.
