UNO Stacko Rules

Let’s get started!

What is UNO Stacko?

UNO Stacko is a card game variant of the popular game UNO. Instead of cards, players use colored plastic blocks in red, green, yellow, blue, and purple.

The goal is to move blocks and not cause the tower to fall over. The player who pulls and places the last block before it falls is the winner. The game includes reverse, skip, draw 2, and wild blocks. 

Players must use only one hand to pull and place blocks but can switch hands. The game is suitable for players above the age of seven and can be enjoyed by an entire family. 

UNO Stacko requires physical tasks, patience, and sound judgment – making it a great game to have in any home.

The Objective of the UNO Stacko game

The objective of the game is to move blocks and not cause the tower to fall over. Therefore, a player must be the one to pull and place the last block before it falls to win the game. 

UNO Stacko rules 

Draw Two Block

If a player pulls a Draw 2 block, then the next player must pull two blocks in their turn instead of one. The second block pulled is the one that the next player must match to. 

Reverse Block

If a player pulls a reverse block, then the direction of play changes and goes the opposite way.  

Skip Block

If a player pulls a skip block, then the next player misses their turn, and the following player goes. 

Wild Block

A wild may be pulled in place of any block at any time. When a wild is pulled and placed on top, the player who pulled it picks the color that the next player must pull.

How to play UNO Stacko?

Setting Up the Game

There are 45 blocks and a loading tray in the UNO Stacko box. The composition of the blocks are as follows:

  • 8 red blocks
  • 8 blue blocks
  • 8 yellow blocks
  • 8 green blocks
  • 3 reverse blocks
  • 2 skip blocks
  • 4 draw 2 blocks
  • 1 wild block. 

A player builds the tower by placing layers of three random blocks at right angles on top of each other. Using the loading tray the player straightens the tower. 

Once the tower is finished play proceeds clockwise. All the numbers, symbols, and colors are randomized with three blocks per layer. Every layer must face in the opposite direction of the layer above it. 

Playing the Game

The first player picks any block and pulls it from the tower, and then places it on top perpendicular to the previous layer. 

Players can only pull blocks from below the topmost finished layer. They can use only one hand at a time to pull a block. However, they can switch hands at any time. 

Players may tap and touch mini blocks on their turn to find loose ones or to straighten the tower so long the player only uses one hand. 

Any block disturbed in this way that is not removed must be restored back to its original position. 

After the player places the block at the top of the tower, his or her turn ends, and the next player goes. 

The next player must now pull a block that matches the color or number of the previous block pulled and place that block beside the previously placed block on top of the tower. This is how the game proceeds.

Ending the Game

When the tower falls, the game ends. The player who placed the last block on top of the tower before it fell is the winner. 

For example, in a four-player game, if player four made the tower fall, player three would be the winner. 

Additional Rules

Use only one hand!

One of the most interesting rules of the game is that players are allowed to use only one hand. They cannot use both hands while pulling the blocks from the tower. However, players are allowed to switch hands. 

Players can use one hand to fix the tower whenever necessary. If, at any point, a player touches the tower with two hands simultaneously, any other player may shout “UNO!” and force the offending player to remove two blocks of any color of their choice.

UNO Stacko rules for colors and numbers

Whatever block was played last, the next block has to be either the same color or same number or a wild block. 

Rules for the layers in UNO Stacko

As the game proceeds, layers are formed one after the other. No block from a completed top layer can be pulled. 

All the blocks pulled must be from the layers below the topmost layer. Also, so long as a layer on top is incomplete, the layer below it will continue to act as the topmost layer. 

When you play 2 players, what to Do?

If you are playing with two players, then skip and reverse blocks act as draw 2 blocks. 

Strategy for winning UNO Stacko

You can use the action blocks to gain an advantage over the opponents. For example, you can use a skip block to prohibit your next player from his or her turn. 

Alternatively, with a draw 2 block, you can compel your next player to draw 2 blocks which may lead to the fall of the tower, making you the winner.
