Blinko

Play Blinko headlessly on Abstract. Provably fair Plinko with on-chain settlement.

Important

• This skill signs on-chain transactions that spend real ETH. Use a dedicated hot wallet with only the funds you're willing to risk.
• Each game costs gas (Abstract chain) on top of your bet amount.
• Your private key is used locally to sign messages and transactions. It is sent to the Abstract RPC and Blinko API as signed outputs only, never as plaintext.
• Agents can invoke this skill autonomously when installed.

Quick Start

Play a Game

export WALLET_PRIVATE_KEY=0x...
node scripts/play-blinko.js 0.001

node scripts/stats.js 0xYourAddress profile

Scripts

| Script | Purpose |

|--------|---------|

| play-blinko.js | Play a full game (auth → create → commit → play → settle) |

| stats.js | View profile, games, leaderboard, honey balance |

Play

export WALLET_PRIVATE_KEY=0x...
node scripts/play-blinko.js [betETH] [--hard] [--v2]

| Flag | Effect |

|------|--------|

| --hard | Hard mode (0% main game RTP, must trigger bonus to win) |

| --v2 | V2 algorithm and config |

Examples:

node scripts/play-blinko.js 0.001                # Normal, 0.001 ETH
node scripts/play-blinko.js 0.005 --hard          # Hard mode
node scripts/play-blinko.js 0.002 --v2            # V2 algorithm
node scripts/play-blinko.js 0.003 --hard --v2     # V2 hard mode

Bet limits: 0.0001 - 0.1 ETH

How It Works

API → Chain → API → Chain

1. Login — Sign message with wallet, get JWT
2. Create — API generates game seed, returns server signature
3. Commit — Call createGame() on-chain with ETH bet + random salt
4. Play — API combines seeds, simulates physics, returns result
5. Settle — Call cashOut() (win) or markGameAsLost() (loss) on-chain

All games are provably fair via commit-reveal scheme.

Game Mechanics

• 10 balls dropped through 8 rows of pins
• Bin multipliers: 2x, 1.5x, 0.5x, 0.2x, 0.1x, 0.1x, 0.2x, 0.5x, 1.5x, 2x
• Bonus: Collect B-O-N-U-S letters to trigger bonus rounds (up to level 9)
• Honey: Earned by hitting special pins (requires a referrer)
