🤖 vs Machine — FREE. Just play: no stake, no charge. That's why nothing is charged when you play the machine. If you win by checkmate in 90+ moves (and own an LPCG) you may mint your battle as an LPCGB 1/1 (mint fee set by DCOT; currently free).
⚔ Versus (owner vs owner) — real stake. Both pay FIRST, before playing:
openMatch, pays). The opponent joins and stakes the same (joinMatch, pays). Both stakes go into the escrow contract — not to the other player.In short: you pay once, upfront (your stake), into the contract — the winner collects automatically from the escrow. If he wins he takes the pot; you don't pay him separately. If it's a draw you get your stake back.
⚠ If you leave the board mid-duel: the clock keeps running. In vs Machine (free) nothing is lost — just come back, or it's only a loss with no money involved. In a staked Versus, abandoning means your time runs out → timeout loss, and the opponent claims the pot from the escrow (your stake is already locked in the contract — don't abandon a staked match). If a joined match is never finished by anyone, after 1 day either player can reclaim both stakes (timeoutRefund) — no funds get stuck.
openMatch / joinMatch / finishmintLost Pixel City Generations Battles — chess played with your fully on-chain pixel warriors.
Lost Pixel City Generations (LPCG) is an 11,104-piece pixel-art collection of chess warriors on Robinhood Chain. Each warrior carries a real Chess Role and Side (Light/Dark) in its metadata — that's how we build 347 complete armies. In this game each NFT becomes a 3D voxel piece on its own square.
Per PvP match the pot is 0.40 (2 × 0.20) and splits:
Only wallets holding ≥1 LPCG can enter PvP or record a score (checked on-chain via balanceOf). If nobody joins your table, your stake is refunded.
balanceOf). Only owners (≥1 LPCG) can score or mint the art.Only the winner (and they must own an LPCG) can mint the match into LOST PIXEL CITY GENERATIONS BATTLES (LPCGB) — a fully on-chain, interactive art collection on Robinhood, open only to winning owners. The art captures the move lines of both players (winner + opponent) as triangular patterns, plus duration, move count and the minter's ETH address. The SVG is rebuilt on-chain by tokenURI() — no server, no IPFS.
The minter can edit the colors of both sides and the background, or randomize an opposite-hue palette (complementary tones across the full chromatic scale) so every pattern is a unique 1/1 — co-created by the 2 players + DCOT.
Micro-payments + community pool + smart contracts + on-chain art = a self-sustaining ecosystem owned by the holders.
Your pixel coach — I explain every button step by step, teach the rules, the versus flow, and how to play the machine free. Ask me anything.
Set an identity so your games & wins are saved to the stats. Pick a quick alias, or connect a wallet (needed for online versus & on-chain minting). We never ask for a seed phrase or private key — only a standard, read-only connect.
Pay the whole LPCG collection (all 11,104 NFTs) at any time. Snapshot current holders, then distribute from the LPCGBDistributor contract, weighted per NFT.
Distribution signs from your deployer wallet in batches (~200 recipients/tx). Deploy LPCGBDistributor.sol, fund it, paste its address, then run batches.
Maximum-activity simulation — how the game looks to a visitor when it's live and full: players online, games in progress, general chat, and minted 1/1 battle patterns from classic games.
Plays opening lines on its OWN copy of the 3D board — a separate frame, so the demo animation never mixes with your real game or the on-chain reads. It narrates each move and loops; ⏸ pause / ⏭ next are inside the frame.
Name a match → ➕ Open match (you pay the fee & become White on your board). A challenger Joins → accepts & pays → the creator Starts (60-second countdown) → play. The winner mints the on-chain art & claims the prize. One live game per board (347 total); when all are busy, play the machine free. Simulation: no real payment — just press the buttons.
Every move is stored on-chain. The 2D animated SVG is a fully on-chain, self-animating replay. Deployer can mint simulations as reference LPCGB battles.
