The Problem We Set Out to Solve

The moment a game rewards players with real cryptocurrency, every vulnerability — a modified client, a memory editor, a cheat engine — stops being a nuisance and becomes a profitable attack. Most games try to detect cheaters after the fact. We asked a different question instead: what if the client never had enough authority to cheat in the first place?

That question became NimJump. The client only renders graphics, reads your inputs, and records them — it never decides your score, coins, rewards, quests, or leaderboard position. All of that is verified independently, on the server.

Built Around Nimiq Pay

Your Nimiq Pay wallet is how you sign in, how your stats are tracked, and how every reward reaches you. Connect your wallet, and you're playing in under a minute. Rewards — quest completions, leaderboard prizes, your own gameplay — are paid in real NIM, directly to that wallet.

Deterministic Simulation

Every level is generated from a deterministic seed, so every obstacle, collectible, and event can always be reproduced exactly. When you finish a run, the client doesn't upload your score, coins, or rewards — it uploads only a compressed replay of your inputs. Nothing else.

The server replays that input log against the same seed, at the same 60Hz tick rate, and recalculates everything itself: every jump, collision, kill, pickup, and score. If it can't reproduce your run exactly, the run is rejected. No manual review, no guessing — just deterministic verification, which is also why a modified client trying to fake a score, complete a quest instantly, or inject impossible gameplay simply doesn't matter: none of those values are ever trusted in the first place.

A World Built to Escalate

The world cycles through 4 distinct biomes — Grass, Desert, Fall, and Sky — each with its own look and its own dedicated pool of enemies, and over 20 distinct enemy types with real behavioral differences, not just reskins. We'll let you discover those in-game.

Difficulty scales with you: as your score climbs, enemies get faster and more alert, up to +15% movement speed and +10% detection range — a smooth, deterministic function of score, never random, which is exactly what keeps server verification possible.

Offline Play, Same Integrity

NimJump works completely offline — it never blocks on a network call before letting you play. Reconnect, and your replay uploads and gets verified exactly the same way it always does. Offline play never bypasses security; it's just convenience layered on top of it.

Replay Technology & Transparency

We don't store gameplay video or full game state — just your inputs, run-length encoded into a byte stream with a small periodic sync marker. A typical ~2-minute match compresses down to roughly 500–700 bytes, meaning 1 GB of storage holds well over 1.5 million fully verified matches.

Every leaderboard score is backed by a replay, and every replay can be watched or shared with a direct link — nothing is hidden behind server calculations.

Daily Quests

Every player gets 5 quests a day, refreshed at midnight and generated deterministically per player — a different, varied mix each day. Completion is checked against the same server-verified replay data as everything else, and rewards are real NIM, paid out as soon as you claim, with no daily cap.

Leaderboards & Stats

Daily, weekly, and all-time leaderboards, ranked by your best server-verified score, with real NIM prize pools for daily and weekly winners. Your stats panel tracks your best runs, kills, rank, recent games, quest progress, and lifetime NIM earned.

NIM earned directly from in-game coins is capped per day to keep that economy healthy — but the cap only applies to coin-derived earnings; quest and leaderboard rewards are untouched by it.

Future Development

Real groundwork is already laid for what's next: additional biomes and enemy types beyond the four currently live, and a 1v1 Competitive VS Mode — create a room, set an entry fee in NIM, and the server verifies both players' replays independently, with the higher verified score winning the pot, using the same trust model as solo play.

Built for Nimiq

Everything here points at one goal: a game where NIM rewards can be distributed with confidence, and where people have a genuine, daily reason to open their Nimiq Pay wallet — not a wallet connected once and forgotten, but a game people come back to.
