Snake and Ladder Game Using Tynker – Step-by-Step Block Coding Guide for Beginners

• 
  

Build a classic Snake and Ladder game using Tynker with this easy, beginner-friendly tutorial. In this project, players roll a dice, move their character using arrow keys, climb ladders, and slide down when bitten by snakes.

This game uses messages, variables, random numbers, collision detection, and turn-based logic, making it a perfect classroom project for learning core programming concepts through block coding.

🛠 Step-by-Step Coding Guidelines

---

Step 1: Arrow Button – Turn Switching & Dice Trigger

Concept Introduced: Turn-based logic

• When the arrow button is clicked

• Check the choice variable

• Send message to Dice

• Switch turn using the choice variable

This helps students understand:

• Variables

• If-else conditions

• Message broadcasting

• Player turn control

---

Step 2: Dice Roll Animation & Random Number

Concept Introduced: Random number generation + animation

Dice receives message →

• Repeat 10 times

• Pick random number from 1 to 6

• Switch costume accordingly

• Wait briefly for rolling effect

• Send movement message

• Display final dice number

Students learn:

• pick random 1 to 6

• Costume switching

• Animation timing

• Event messaging

This creates a realistic dice rolling effect.

---

Step 3: Player Movement Using Arrow Keys

Concept Introduced: Conditional keyboard control

• Arrow keys change X and Y positions

• Movement allowed only if it’s the player’s turn

Students understand:

• Coordinate movement

• Conditional input control

• Turn-based restriction

This is a great introduction to keyboard-based navigation in games.

---

Step 4: Display Movement Instructions

Concept Introduced: User guidance with messages

When movement message is received:

• Display how many steps to move

This:

• Improves user experience

• Reinforces dice result

• Connects game logic with player action

---

Step 5: Ladder Detection (Green Chip)

Concept Introduced: Collision detection with delay logic

When touching Green Chip:

• Track detection timing

• Prevent instant trigger

• Glide to ladder top

Students learn:

• Repeat while loops

• Collision timing

• Glide movement

• Position control

This simulates climbing a ladder.

---

Step 6: Snake Bite Detection (Red Chip)

Concept Introduced: Game penalties & collision handling

When touching Red Chip:

• Detect sustained contact

• Display message

• Glide to snake tail position

This teaches:

• Negative game events

• Position resetting

• Game challenge mechanics

---

How to Play the Game

1. Click the Arrow Button to roll the dice

2. Observe the dice number

3. Move using arrow keys

4. Climb ladders

5. Avoid snakes

6. Take turns and reach the finish line first
