This comprehensive guide will walk you through everything you need to know to easily trigger checkmate in Grand Garden and unlock the coveted “Lost in the Game” achievement. As someone who’s spent countless hours navigating the chess puzzle amidst the chaos of 36-player battles, I’m here to share the exact strategies, hero recommendations, and step-by-step solutions that will have you unlocking this achievement in no time.

Understanding the Checkmate Achievement (May 2026)

The Checkmate achievement, officially known as “Lost in the Game” in Marvel Rivals, is part of the Chronoverse Saga achievement set introduced in Season 5. This achievement tasks you with “Trigger 1 checkmate in Grand Garden” and rewards you with 5 Achievement Points toward earning free Units. What makes this achievement particularly challenging is that it can only be completed in the 18v18 Annihilation mode on the Grand Garden map, which was released on November 27, 2025, as part of the game’s first anniversary celebration.

How to Get Checkmate Achievement in Marvel Rivals 18v18 Mode?

Prerequisites Before Starting

Before attempting the Checkmate achievement, you need to ensure you have the right conditions:

1. Correct Mode Selection: Queue for 18v18 Annihilation mode in Quick Play or Arcade
2. Right Map: You must load into Grand Garden (other maps won’t work)
3. Public Match Only: Custom matches do not count toward achievement progress
4. Hero Selection: Choose mobile, ranged heroes for best results

The Grand Garden map features a massive chess puzzle area in the center of the arena, but finding it and solving the puzzle amidst 35 other players can be incredibly challenging. That’s why I’ve broken down the entire process into manageable steps.

Step 1: Navigating to the Chess Puzzle Area

The chess puzzle is located in a dedicated sub-area in the center of the Grand Garden arena, away from the main objective fighting. Here’s exactly how to get there:

From Your Spawn:

1. Move toward the middle of the Grand Garden arena
2. Look for a large central structure and a water-tower-like building that stands out from surrounding platforms
3. Enter the structure via the “water tower” side
4. Inside, you’ll find an elevator that takes you down to an underground hub area beneath the main arena
5. Follow the underground corridor forward from where the elevator drops you off
6. A few steps ahead, you’ll reach a chamber that opens back upward to the surface platforms where the giant chess pieces stand

Once you’re up top, you’ll see enormous chess pieces on separate stone platforms, with Gambit standing on a high platform near the board. This is the chess area you need to work with.

Step 2: Choosing the Best Heroes for the Chess Puzzle

While almost any hero can technically complete the puzzle, some make it significantly easier in the chaotic 36-player environment. Based on extensive testing, here are the top recommendations:

Tier 1 Heroes (Highly Recommended)

Hero	Why They Excel	Key Advantages
Angela	High mobility + sustained ranged damage	Can stay airborne while chipping pieces, excellent escape tools
Human Torch	Strong vertical mobility + reliable attacks	Quick target switching, good area damage, flight capability

Tier 2 Heroes (Good Alternatives)

Hero	Why They Work	Considerations
Gambit	Ranged attacks + thematic connection	Good damage output but less mobility than top picks
Storm	Area damage + flight	Can hit multiple pieces but slower single-target damage
Iron Man	Flight + sustained damage	Good mobility but requires more precise aiming

Why Mobility Matters: In 18v18 matches, you’ll constantly be interrupted by enemy players. Mobile heroes can quickly reposition after being knocked away, escape dangerous situations, and return to the puzzle area faster. Flying heroes have the additional advantage of being able to work on pieces from angles that ground-based heroes can’t easily reach.

Step 3: Understanding the Chess Puzzle Mechanics

The chess puzzle revolves around physically moving giant chess pieces by damaging them. Each piece will slide along its lane and stop on a specific tile if you keep hitting it. The goal is to move all involved pieces into a configuration that checkmates the opposing king.

Key Puzzle Behaviors to Watch:

• Pieces glow when targetable – If something isn’t glowing, it has either been moved already or the puzzle is in a bad state
• Grass rings indicate correct placement – When a piece reaches its correct destination, grass grows at the base of that platform
• Chess rules apply – You must move pieces in an order that respects actual chess logic
• Reset functionality available – If you mess up, you can reset the entire puzzle

The Critical Chess Logic Constraints

This is where most guides fall short, but understanding these constraints is crucial for success:

1. Pawn must move first – If you don’t move the pawn immediately, it will later auto-advance when you try to adjust it for an en passant-style capture, breaking the intended solution
2. King must move before the knight – If the knight moves too early, it occupies the king’s ideal destination square and blocks the final checkmating layout
3. Bishop must move after the knight – The bishop’s final position depends on the knight vacating its starting square
4. Queen is flexible but never first – The queen always goes to the same final tile, but moving it before the pawn causes the puzzle to desync

Step 4: The Exact Piece Order to Trigger Checkmate

After extensive testing across multiple matches, I’ve confirmed the definitive sequence that works every time. Follow this order exactly:

1. Pawn – Attack until it moves into position and grass appears at base
2. King – Move next, ensuring proper positioning for checkmate
3. Queen – Place after king is correctly positioned
4. Knight – Move only after king is in place (critical!)
5. Bishop – Final piece to complete the checkmate configuration

Pro Tip: Do not touch other pieces in between steps, and be careful that teammates don’t “help” by hitting pieces out of order. In public matches, this is one of the biggest challenges – other players may accidentally (or intentionally) disrupt your sequence.

Step 5: How to Execute Each Move

Every move is performed the same way: stand on a platform with the appropriate piece and keep damaging it until it finishes sliding into place and grass appears. Here are specific tips for each piece:

Moving the Pawn

• Target the pawn piece first (it’s usually the smallest piece)
• Use sustained fire until it slides forward and grass appears
• This piece is crucial – if moved incorrectly, the entire puzzle breaks

Moving the King

• The king is typically the largest piece
• Position yourself to have clear line of sight
• Continue attacking until it moves to its designated square
• Watch for the grass indicator to confirm correct placement

Moving the Queen

• The queen is usually distinctive in appearance
• Move it only after both pawn and king are correctly placed
• Ensure you’re not accidentally hitting other pieces

Moving the Knight

• This is where many players fail – the knight must move AFTER the king
• If moved too early, it blocks the king’s path
• Wait for clear confirmation that king is properly placed

Moving the Bishop

• The final piece in the sequence
• Move it only after the knight has vacated its starting position
• Once placed correctly, the checkmate sequence should trigger

Step 6: What Happens When You Successfully Trigger Checkmate

Once every required piece is in its correct position, the game recognizes a checkmate on the invisible underlying chessboard. Two things happen immediately:

1. The large platforms shift and a hidden room opens below the chess area
2. A floating walkway appears connecting Gambit’s high platform to the far side of the chessboard, creating a permanent bridge for the rest of the match

To Complete the Achievement:

1. When you see the platforms move, jump down into the newly revealed room underneath the chessboard
2. Inside, you’ll find a normal chessboard laid out in a static checkmate position
3. Entering this room after solving the puzzle is what fulfills the “Trigger 1 checkmate in Grand Garden” condition

Critical Final Step: From this point on, you only need to remain in the match. Leaving early can prevent Lost in the Game from registering on your account. I’ve seen players lose their achievement progress by disconnecting or leaving immediately after solving the puzzle – don’t let this happen to you!

Step 7: How to Reset the Chess Puzzle if Something Goes Wrong

With 35 other players on the map, someone will often hit the wrong piece or disrupt the sequence. When that happens, you need to reset the entire board:

Reset Process:

1. From the main chess platforms, drop back down into the underground area beneath the board
2. Look for a small standard-sized chessboard embedded in the floor a few steps forward from where Gambit stands above
3. This board has an interactable button – interact with the reset button
4. This snaps all giant pieces back to their starting positions and restores their targeting logic
5. Return to the upper platforms and repeat the piece sequence: Pawn → King → Queen → Knight → Bishop
6. Confirm that each base sprouts grass before moving to the next piece

When to Reset:

• If you notice the wrong piece has moved
• If a piece stops being targetable unexpectedly
• If the queen cannot be targeted (someone else moved it or order was broken)
• If you’re unsure about the current state of the puzzle

Common Issues and How to Avoid Them?

Other Players Moving Pieces Out of Order

This is the most common frustration in public 18v18 matches. Teammates and enemies alike may hit random glowing pieces, either intentionally or accidentally.

Solutions:

• Work on the puzzle during quieter phases of the match (after big team fights)
• Reset immediately if you notice disruption
• Consider playing during off-peak hours when fewer players are around
• Communicate with teammates if possible (though coordination is difficult in 18v18)

Queen Cannot Be Targeted

If the queen stops being targetable even though you have not moved it yourself, either:

• Someone else moved it earlier, or
• The piece order was already broken by a different move

Solution: Use the reset board below to return the puzzle to a clean state.

Dying While Working on the Puzzle

Grand Garden Annihilation is extremely chaotic. Expect to be killed while focusing on pieces or exploring the underground area.

Solutions:

• Use mobile heroes (Angela, Human Torch) as recommended
• Time your attempts during quieter phases
• Be prepared to return quickly after respawning
• Consider the puzzle a mid-match detour rather than something to rush

Custom or Private Matches Not Counting

Only public matches on Grand Garden Annihilation award Lost in the Game. If you solve the puzzle in a custom lobby, you can still see the room and walkway, but the achievement will not unlock.

Solution: Always queue for public 18v18 Annihilation matches.
