— Everybody is a winner —
NgMastermind rewards knowledge with real cash rewards and prizes.
This is NOT a game of luck or chance — only knowledge
and speed of thought wins.
Know and learn more about Nigeria, Africa, and the world, while competing for real rewards.
NgMastermind may be the only game of its kind in the world that allows you to earn real rewards while completely offline. Once installed and registered, you need absolutely no internet connection to play — literally forever. The full game experience, all 47+ categories, and every puzzle are available on your device without data or Wi-Fi.
When competing for prizes, you only need a brief internet connection to upload your scores. Everything else — gameplay, learning, and accumulating points — happens entirely offline.
Players only win when their scores cross the qualifying mark — like a pass mark in any examination. The players with the highest scores, in the fastest times, are simply the winners. You get rewarded for your knowledge and your speed of thought.
Playing daily keeps the brain sharp and the mind alert. Every score you accumulate converts to points redeemable for real-world value. Game Hints are purchased ONLY by payment transfer from the credit balance in your Mobile Banking Wallet.
Play word games, score points, and earn rewards — all while learning about Nigeria, Africa, and the world. Edutainment at its very best.
Register and fund a Mobile Banking Wallet with a small one-time setup fee. This permanently activates your account for all game modes — no further charges to play Knowledge & Fun.
Play for Cash & Rewards by purchasing an affordable daily Hints Pack, or play for Knowledge & Fun completely free — forever, after your one-time wallet setup. Both modes are fully offline. Game Hints purchased ONLY by transfer from your Mobile Banking Wallet.
Search grids and solve crosswords across 47+ categories — Nigerian states, African nations, world capitals, currencies, languages, and 5,000+ English words.
When ready to compete, connect briefly to upload your scores and update the leaderboard. Play offline the rest of the time — daily, weekly, or monthly connection: you choose.
Top scorers win cash prizes. All players accumulate points redeemable for cash, airtime, or internet data after a qualifying period. Everybody wins something.
Whether you're here to learn or to earn, NgMastermind has a mode designed for you — and both modes work completely offline.
Compete against players nationwide for daily, weekly, and monthly cash prizes delivered straight to your Mobile Banking Wallet. Knowledge is your only advantage.
After your one-time wallet registration, this mode is completely free. Play as often as you want, whenever you want — entirely offline, no extra charges, ever.
NgMastermind's tiered rewards system ensures no player ever leaves empty-handed. Every score always counts.
The highest scorers each day receive cash prizes credited directly to their Mobile Banking Wallet. Upload your scores to qualify. Prize amounts published in the app.
Weekly cumulative scores are tallied each period. The top players of the week receive cash rewards. One brief score upload per week qualifies you.
Every month, the players with the highest cumulative scores are celebrated and awarded cash prizes. Consistency and knowledge are rewarded.
Didn't win cash this round? Every point you score is stored. After a qualifying period, redeem them for cash, airtime, or mobile internet data. Everybody wins something.
