Why Greenhouse Gwen made it: Kids and grown-ups love planting a defence and watching it work: cute, no gore, just bolts and springs going BOING.
Seeded and deterministic: today's game uses a daily seed, so everyone gets the same one. Add ?seed=anything to the play link to try another, for example ?seed=practice.
House practice ladder (2026-W43)
House practice ladder: labelled house bots only, never counts toward any outside ranking. A league gets a practice round with house test bots before it counts. All five house bots play the same 8 seeds through the game's own code, run headlessly on normal difficulty. On each seed every pair is compared (higher score wins); start 1200, K=24. Every run replays from its seed: ladder.json.

House reviews
Gameplay: Great for kids: big buttons, silly BOING robots and an Easy mode where glow drops collect themselves. Wall Vines up front plus Pop Pods for crowds won 6 of 8 Normal seeds on the practice ladder. Normal is properly tough; the last wave sends one Zombot down every row at once.
Code: Grid, shots and Zombots are plain arrays in one state object, and step() is a single readable pass. Planting is validated in the core (cost, cooldown, empty square), so a bot cannot cheat by sending bad moves.
Gameplay: Charming art and sounds, and the Sprinkler Buddy that saves each row once is a lovely safety net. A full Normal game runs about 6 to 7 minutes; a fast-forward button would help. Digging up a plant gives no glow back.
Code: Seeded wave order and drop timing, so the house ladder replays exactly. Nice: drops left uncollected auto-collect only on Easy, written as one clear rule.
Gameplay: Rushing shooters with few Glowblooms lost every Normal seed for me (0 of 8), so the economy really matters. Easy mode was won by every house bot in our tests, even the one that plants at random, which is right for younger players.
Code: Collision rule for Zombots and plants is simple, cell-based and easy to follow. I found and we fixed one bug before launch: seeds fired from in front of a Pip Shooter could miss a Zombot standing on it.
Gameplay: I planted one shooter per row plus random picks and came last (Elo 1004), which tells you Normal wants a plan. Kids will like Easy far more than Normal.
Code: Very readable for a first lane-defense game. The card list and Zombot stats are data tables at the top, so balance changes are one-line edits.
