TL;DR: The Peace-Protocol Cheat Sheet If you’re currently hearing "STOP GRIEFING ME" or "HE STOLE MY LOOT" echoing from the basement, here are the top 2025 picks to restore order. These focus on cooperation over competition:
- Best for Creative Minds: Minecraft (Creative Mode)
- Best for Problem Solvers: Snipperclips
- Best for Laughs (and Chaos): Untitled Goose Game
- Best for Older Siblings: It Takes Two
- Best for Cozy Vibes: Stardew Valley
We’ve all been there. You think you’re being a "cool parent" by letting them play together, and ten minutes later, someone is crying because their older brother "accidentally" dropped them into lava or sold their rarest pet in Roblox.
The problem isn't usually the kids; it’s the game mechanics. Most popular games—from Fortnite to Super Smash Bros. Ultimate—are built on a "Winner/Loser" binary. When you add a skill gap (like a 10-year-old playing against a 6-year-old), that binary becomes a recipe for a meltdown.
To get "Sibling Peace," we have to move away from Zero-Sum Games (where one person’s win is the other’s loss) and toward Positive-Sum Games (where you literally cannot win unless you work together).

In these games, the players share a single goal. If one fails, they both fail—or better yet, they help each other up.
This is the gold standard for sibling harmony. Players control two paper characters who have to literally snip pieces out of each other to fit into shapes or solve puzzles. It’s impossible to play without talking, and because the puzzles require both players, the "big kid" can’t just run ahead and do everything.
- Ages: 5+
- Conflict Level: Low. It’s more about "oops, I cut you wrong" than "I beat you."
What’s better than one horrible goose? Two horrible geese. This game used to be single-player, but the update allows two kids to team up to terrorize a peaceful village. It’s hilarious, low-stakes, and turns the "aggression" toward the NPCs (non-player characters) rather than each other.
- Ages: 6+
- Conflict Level: Very Low. Shared mischief is a powerful bonding tool.
Warning: This game is literally about a couple going through a divorce (they get turned into dolls and have to work together to get back to their daughter). It sounds heavy, but the gameplay is some of the best co-op ever designed. It requires two people. You cannot play it alone. Note: There is some "cartoon violence" and one notoriously traumatizing scene involving a toy elephant that you might want to read about in our guide.
- Ages: 10+ (due to some complex themes and tricky platforming)
- Conflict Level: Moderate (requires high coordination).
If your kids have a "creator" mindset, these games allow them to exist in the same space without necessarily needing to fight over who has the most "kills."
If they are playing Survival Mode, they’re going to fight over resources. If they play Creative Mode, they have infinite blocks and can build a "Skibidi Toilet" museum together.
- Pro Tip: Set up a "Shared World" and establish a "No Griefing" rule (no breaking each other's stuff) before they even pick up the controller.
- Ages: 7+

Roblox is a minefield of "brain rot" and predatory microtransactions, but Build a Boat for Treasure is a gem. Siblings have to build a single vessel together to survive a river. If the boat is poorly built, they both sink. It encourages engineering and shared planning.
- Ages: 7+
- Conflict Level: Low to Moderate (if the boat sinks, blame might be shifted).
Sometimes the "war" is just about overstimulation. These games lower the heart rate.
The multiplayer mode allows kids to run a farm together. One can go fishing, the other can plant corn, and another can go explore the mines. They share a bank account (usually), so they’re working toward a common goal of buying that next big barn upgrade.
- Ages: 8+ (requires a fair amount of reading)
- Conflict Level: Very Low. It’s the digital equivalent of gardening together.
While the local co-op (playing on the same screen) is honestly a bit clunky and frustrating, having siblings visit each other's islands to trade fruit or furniture is a lovely, low-conflict way to interact.
If you are looking for a quiet afternoon, avoid these unless your kids have the emotional maturity of a Zen monk:
- Mario Kart 8 Deluxe: The Blue Shell was designed by scientists to destroy sibling relationships. It is the definition of "unfair."
- Super Smash Bros. Ultimate: High-intensity button mashing often leads to physical "IRL" shoving.
- Among Us: The entire game is based on lying to your friends and family. For some siblings, this is fun; for others, it’s a betrayal they won’t forget by dinner time.
One of the biggest triggers for sibling wars is the Skill Gap. If a 12-year-old is playing a game with a 7-year-old, the 12-year-old will naturally dominate.
The Solution: Look for games with "Asymmetric Co-op."
- In Super Mario Bros. Wonder, one player can be Yoshi or Nabbit, who don't take damage. This allows the younger kid to play along without "dying" and ruining the fun for the older kid.
- In Kirby and the Forgotten Land, the second player (Bandana Waddle Dee) has a slightly simpler role, making it great for a younger sibling to "help" without the pressure of leading.
Before you hand over the controllers, have them "sign" (or just agree to) a few ground rules. We call this the Screenwise Sibling Treaty:
- The "Pause" Clause: If one person says "stop" or "I’m frustrated," we take a 2-minute breather.
- No "Griefing": No intentional destruction of something someone else worked on.
- The "Carry" Rule: The older/more skilled player is the "mentor," not the "boss." Their job is to make sure the younger player is having fun.

Not all screen time is created equal. If your kids are screaming at each other over Fortnite, it’s not necessarily a "behavioral issue"—it might just be a "game design issue."
Switching to cooperative titles like Snipperclips or Stardew Valley changes the dynamic from "Me vs. You" to "Us vs. The Game."
- Audit their library: Look at their current games. Are they mostly competitive?
- Try a "Co-op Saturday": For one weekend, only allow games where they have to work together.
- Check the WISE scores: Before buying a new multiplayer game, check the Screenwise WISE score to see how it ranks for social emotional health.
