In mathematics the prime numbers (also called “primes”) are natural numbers greater than 1, divisible only by 1 and by themselves. "Primes" is a mathematical game of search of natural numbers that added together give as result prime numbers. For each level of the game, will be shown: - a TABLE of prime numbers formed by 30 prime numbers (that will change at every level of the game) - a MAP formed by 16 boxes containing natural numbers which, added together, will give as result at least 5 primes among those listed in the TABLE of prime numbers In the TABLE, primes will be highlighted: - in red if it exists in the MAP at least one combination (sum) of natural numbers that give as result the prime number highlighted in red (there is certainly a combination in the MAP) - in blue if it is not certain that there is in the MAP a combination (sum) of natural numbers that give as result the prime number highlighted in blue (may or may not exist a combination in the MAP) An automatic calculator (indicated by SUM) will assist You in the sum of natural numbers that You have selected in the MAP (combination). For each level, You will have 3 minutes of time to find 5 primes among those listed in the TABLE of prime numbers: so, you'll have to find 5 combinations of natural numbers in the MAP that will give as result 5 distinct prime numbers. This game increases the visual memory and the speed for mathematical calculation. It will also help You to store a large amount of prime numbers. Have fun with Primes...

One low price guarantees no ads, includes all features, and we do not collect any personal data. Shut The Box rules vary among communities. With this app, you can tailor your experience to your own rules. You decide how many tiles to flip (9, 12, 18, 24), how many dice to roll (1 to 5) and how many players can share the same app (up to 8). General Rules: The goal is to score the least amount of points. Points are the sum of all the open tiles. You want to "flip" or close the tiles to reduce your points. To play, each player rolls the dice until they can no longer flip their tiles. To flip a tile, a player rolls the dice and they sum the total. Next, the player "flips" any of the tiles that add up to the sum of their dice. Example: 2 dice are rolled that add to 7. The player can flip a 7, or the 6 and 1, or the 5 and 2, or the 4 and 3. If a player cannot flip the tiles that equal the sum of their dice, their turn ends and the next player begins. The lowest score for each round wins! No need to worry about bringing the boxed game....you now have it everywhere you go! Enjoy.
