— Everybody is a winner —
NgMastermind rewards winning word-search and crossword puzzles with real cash 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 daily, weekly, and monthly rewards.
NgMastermind may be the only game of its kind in the world that allows you to earn real money while completely offline. Once the app is installed and you have 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.
If you are competing for daily cash prizes, you only need an internet connection once per day — for less than five minutes — simply to upload your scores to our server and update your personal leaderboard standing. Competing for weekly prizes? One upload per week. Monthly prizes? One brief connection per month is all it takes. Your scores accumulate safely on your device until you are ready to connect.
No subscription. No data bundle. No Wi-Fi required. Just play, accumulate scores, and upload when convenient — then collect your winnings.
Players only win when their scores cross the qualifying mark — like a pass mark in any examination. The three players with the highest scores, in the fastest times too, are simply the winners. You get rewarded for your knowledge and your speed of thought!
But there is more — playing daily not only keeps the brain sharp and the mind alert; it is like learning and having fun at absolutely no cost, since whatever scores are accumulated are convertible to points which are redeemable in cash, airtime, or internet data, which offsets prior expense on the daily Hints. Please note: Game Hints are purchased ONLY by payment transfer from the credit balance in the Mobile Banking Wallet.
Play word games, score points, and win cash rewards — all while learning about Nigeria, Africa, and the world. It is edutainment at its very best.
Register and fund a Mobile Banking Wallet with just ₦200 to receive your winnings. A one-time setup that unlocks the game permanently — no further charges to play for Knowledge & Fun.
Play for Cash & Rewards by buying a ₦100 Hints Pack, or play for Knowledge & Fun completely free — forever, after your one-time wallet setup. Both modes are fully offline. Game Hints can be purchased ONLY by payment transfer from the credit balance in 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 — under 5 minutes — to upload your scores and update your leaderboard. Daily, weekly, or monthly: you choose how often you connect.
Top 3 daily, weekly, and monthly scorers win cash. Others accumulate points redeemable for cash, airtime, or internet data after 60 days.
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 ₦200 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 three highest scorers (fastest times as tie-breaker) each day receive cash prizes credited directly to their Mobile Banking Wallet. Upload your scores once daily to qualify.
Weekly cumulative scores are tallied every 7 days. The top three players of the week receive additional cash rewards. One score upload per week is all you need.
Every month, the three players with the highest cumulative scores are celebrated and awarded with cash prizes. One upload per month qualifies you for the monthly competition.
Didn't win cash this round? Every point you score is stored. After 60 days, redeem them for cash, airtime, or mobile internet data. Everybody wins something.
These simulations show the scores that won the last daily, weekly, and monthly prizes — so you know exactly how far or how close you are to the top.
All winnings are delivered to your personal Mobile Banking Wallet. Setup is simple, secure, and completely one-time.
