"Square" and "Tower" - Two "Dice as building block" games

Square:

1. Each player must construct a square of 4 dices by 4 dices.
2. Before they add each dice to a square they roll the dice and then place it within the square with the dice roll facing upwards.
3. However, an odd numbered roll cannot be placed, either vertically or horizontally, next to another odd numbered roll or, in other words, each square should be made up of rows that are (both horizontally and vertically) odd, even, odd, even or even, odd, even, odd.
4. The first player to complete their 4 dice by 4 dice square is the winner.

Tower :

1. Players take turns rolling a six sided dice. The player that rolls the highest number wins the dice.
2. They do this again and again, taking dice from a box or pile of dice
3. And each time a player wins a dice they must balance it on top of the dice they have already won, building up a tower of dice.
4. When all the dice are used up, the winner is the player with the tallest tower.
5. If a players tower falls down or is accidentally knocked down by THEM then they lose the game.
6. If part of a players tower falls down then they cannot simply put back the dice that have fallen down; those dice have to be rolled for again and won.
