What the game is

It's a strategy roguelite on a bingo card. Instead of waiting for the caller, you pick the balls from a tray. The marks stay on the card between hands, so you set up rows, columns and diagonals over several turns and close them all at once. Before every play you see the exact score (CHIPS × MULT), no guessing. 77 jokers, 29 keepers that each bend one rule, 12 stops in 4 rooms per run, a daily seed and no timer. 9 languages, Windows and Linux.

Here are a few things from the build that might be useful to other Godot devs.

1. A deterministic core with no nodes

The rules live in a deterministic core with no nodes: plain scripts with a seeded RNG and exact save/restore of the whole state. With the same seed, a run always plays out the same way.

2. The preview is the result, and the tests prove it

The score preview is computed by the same engine without touching the state. The test suite checks simulate(a) == apply(a) across many seeds and random moves, so the number you see before you play is exactly the number you get.

3. The whole UI is drawn in code with _draw()

Buttons and panels are all drawn in code. That paid off when the game went to 9 languages: not a single image had to be redrawn.

4. Chinese and Japanese fonts subset with pyftsubset

The Chinese and Japanese fonts are subset from Noto Sans CJK with pyftsubset, keeping only the characters the game uses. Every time new text is added, a test checks that no character is missing.

5. Coloured keywords inside plain Labels

"+30 chips" in blue and "+1 MULT" in red inside plain Labels come from a tiny canvas_item shader over get_character_bounds() rects, so the text layout never changes.

6. A trailer recorded with Movie Maker

The trailer was recorded with Godot's Movie Maker by restoring real game states, so all 9 language versions share the same frames.

About AI

AI disclosure: some of the art is AI-generated (many of the joker cards, most keeper portraits and the story illustrations), and so is the music (made with ACE-Step). The texts and the 9 translations are AI-assisted, and I build the game with AI coding agents (Claude and Codex) that I direct and review. The balls, the bingo cages, the mechanical keepers and some jokers are Blender renders, the UI is drawn in code, and the sound effects are synthesized by script. Nothing is generated by AI while you play.
