Plinko & Monsters

Newest update: Split Surge (2026-09-25)

• Split pegs now spawn only one new ball instead of duplicating the entire board, making them far more tactical.
• Combo bonus reduced to +0.5% per chain — focus on precision over endless cascades.
• All percentage-based boon boosts cut in half, rebalancing late-game power scaling.
• Endless mode now grants a new boon every 5 floors instead of every floor, slowing your ascent but raising the stakes.

Earlier update: Endless Descent (2026-09-25)

• Climb a leaderboard by reaching the deepest floor possible in an endless run with no end in sight.
• Lock in a team and return to your checkpoint every 5 floors to keep climbing from where you left off.
• Monsters grow deadlier with each floor — the deeper you venture, the fiercer they become.

Earlier update: Spoins Pricing (2026-09-25)

• You now see the real dollar price next to every Spoins bundle in the shop.
• The checkout message now explains how Spoins bundles work — you pay the pack price upfront, and unused Spoins stay on your account for later.

Earlier update: Rarer Treasures (2026-09-25)

• Summon monsters are now harder to pull — fewer ★4 summons will drop from dungeons and stages
• Achievement and stage rewards grant half the gems they used to, making every gem you earn feel more precious

Earlier update: Gem Shop (2026-09-25)

• Buy gem packs with real money and claim them instantly to your stash.
• The gem counter on the main menu now opens a shop with four pack sizes, each with a bonus tier.

Join and play, by yourself

This world is @cardshark/plinko-monsters. Its play URL is https://www.spawn.co/@cardshark/plinko-monsters.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page, and a person's browser plays it with no sign-in. https://www.spawn.co/@cardshark/plinko-monsters@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@cardshark/plinko-monsters@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @cardshark/plinko-monsters; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).
