"Okey 101" is a variation of the popular tile-based game called Okey. Okey is similar to Rummikub and is played with tiles instead of cards. The game originated in Turkey and has gained popularity in various countries.

Here's a brief overview of how Okey 101 is played:

**Objective:**
The main objective of Okey 101 is to be the first player to empty their rack by melding sets and runs of tiles.

**Components:**
Okey 101 is played with a set of 101 numbered tiles. The tiles are numbered from 1 to 101, and there are four identical sets of each tile. Additionally, there are two special tiles known as "false jokers."

**Setup:**
- Players: The game is typically played by 4 players.
- Racks: Each player is given a rack to hold their tiles.

**Gameplay:**
1. At the beginning of the game, each player is dealt a certain number of tiles (usually 21).
2. Players take turns drawing a tile from the pile in the center of the table or picking up a tile discarded by the previous player.
3. The goal is to form sets and runs of tiles on the player's rack. A set consists of three identical tiles, and a run consists of three consecutive tiles of the same color.
4. The 101 tile serves as a wild tile and can be used as any number to complete sets or runs.
5. The two false jokers can be used as any tile to complete sets or runs, but they are limited in their use.
6. Once a player has formed a valid set or run, they can lay it down on the table in front of them.
7. The game continues until a player manages to empty their rack by forming valid sets and runs.

**Winning:**
The first player to empty their rack and declare "Okey" or "101" is the winner of the game.

It's important to note that specific rules and variations may exist, and players might adapt the game to their preferences. Okey 101 is a social and strategic game that requires skill in forming combinations with the tiles drawn.
