Version 1.1 is here!
Greater than and less than. Thats what Number Duel is all about. Simply tap the card that contains the larger value to score a point. Reach 21 points and your task is done. Easy, right? Not when youre racing against the clock and are dealing with negative numbers. And dont even think about guessing - you lose 3 points for every wrong answer!
Once you think youve got it mastered you can upgrade to try sums, fraction, decimals and more!
Number Duel is a great way to build your number sense or just exercise your brain.
