Slingo — part slots, part bingo, all luck — built with miso and compiled to WebAssembly. Two tables: a faithful clone of the 1994 AOL classic on green felt, and a modern neon-styled remix.
- 🎲 A 5×5 bingo-style card (columns 1–15 … 61–75) and 20 spins of five reels, one under each column — matches mark themselves
- 🃏 Jokers pause the table: pick any open tile in that column (super jokers pick anywhere) — glowing tiles show your options
- ⌨️ Space or Enter spins; a screen-filling SLINGO! slam when a line lands
- 🔊 Sound effects synthesized live with the Web Audio API (zero assets)
- ✨ Built on
Miso.Lens,Miso.CSS, andMiso.CSS.Color
The published scoring of the original AOL game (per the archived Encyclopedia Gamia / Wikipedia scoring table): +200 a number, +1,000 a slingo or a coin, and 3/4/5 jokers in one spin pay 1,000 / 2,500 / 10,000. Only the center reel can go 🌟 super, and a super joker is played first. The 😈 devil halves your score unless the 😇 cherub shoots it (about half the time). 🔄 free spins are held in hand to pay for spins 17–20, which cost 500–2,000 points. A full card is worth 6,000–11,000 — the fewer spins you needed, the fatter the bonus. The look to match: green felt, beveled cream tiles, chrome reels, a big red spin button, and a gold coin slapped on every mark.
😈 Devils halve your score on the spot; 😇 cherubs stay in hand and block them; 🪙 coins (+50) and 🔄 free spins sweeten the reels. 12 slingo lines at +200 each, +20 per tile, and a +1000 full-card jackpot plus +100 for every spin you didn't need — all in neon gold, pink, and cyan on deep violet velvet.
