When one phone has to do the job
Two-player games on one phone are a fairly good fit during a power cut, with one obvious catch. You are both sharing the same battery. If the lights are out, the router is dead, and nobody knows whether this is ten minutes or three hours, that matters.
Still, pass-and-play head-to-heads solve a few problems at once. They work in one spot. They do not need a signal once they have been loaded before. And they give two people something structured to do without turning the room into a talent show.
In GameJar, the two-player-games that fit this category are Connect Four, Dots & Boxes, and Salvo. All three can be played by two people passing one phone or tablet. There is no online multiplayer to set up, which is useful when the router has joined the blackout.
What a game needs during a power cut
A power cut changes the standards a bit. The question is not just whether a game is good. It is whether it is good here, during-a-power-cut, with a dim room, a half-charged phone, and no clear end point.
Here is what matters.
- Short turns. A game should let each person take a turn quickly. Long stretches waiting for the other person to think are less charming by torchlight.
- Low fuss. No router, no pairing, no accounts, no hunting around for settings. Open it and get on with it.
- Quiet play. If the house is already tense, something calm helps. Head-to-heads are fine. A digital drum solo is not relevant here, thankfully.
- Readable screen. In a dark room, clear boards and simple moves beat tiny details.
- Reasonable battery use. If you would rather not drain the phone, games that work well in short rounds are safer than ones that tempt everyone into a long, uninterrupted campaign.
- No signal needed. After one online visit, GameJar stores the games on the device, so they work with no signal in airplane mode.
The other thing worth saying plainly is that two-player games on one phone are best when both people are actually willing to share the phone. If one child treats every turn as a constitutional right, you may prefer tea and silence.
How the games hold up
Connect Four
This is probably the safest choice during a power cut. The board is clear, the rules are already familiar to most people, and each turn is one quick decision. That makes it good when attention is short and the room is not exactly festive.
It also suits low battery better than many games because rounds are compact. You can play one game, stop, and put the phone down. You do not have to commit to a long session just because you opened it.
As pass-and-play goes, it is clean. Both players can see everything they need at once. No hidden information, no awkward shielding of the screen, no debate about whose thumb was in the way. In a dark room, that helps.
The mild downside is that it can become repetitive if you play many rounds in a row, especially if one person has worked out a decent opening pattern and intends to mention this often. But for short head-to-heads, it is the best fit of the three.

Dots & Boxes
Dots & Boxes is quieter and slower than Connect Four, which can be either good or bad depending on your household. If you want something calm, methodical, and low drama, it has a case. Players take turns drawing lines, trying to complete boxes and avoid handing over easy points.
During a power cut, that slower pace can work well. There is no rush, no hidden setup, and not much visual clutter. You can play while talking, while waiting, or while pretending the boiler will somehow fix itself if everyone looks disappointed enough.
Its weakness is length. A game can stretch out, especially if both players are cautious. That is fine if you are settled in one place and trying to pass time. It is less ideal if battery is tight and you want something with a clear, quick finish.
For older kids, though, the trade-off may be worth it. There is enough room for planning and little traps, which keeps it from feeling like a game made for much younger children. It respects the fact that your 11 year old can think ahead and would prefer not to be patronised by a dancing cartoon anything.
Salvo
Salvo is the most atmospheric of the three, which sounds grander than necessary, but it is true. Each player hides four ships on a 7x7 grid and tries to find the other player's first. On one device, you pass the phone back and forth, with a cover so neither player sees the other's board.
That hidden-information setup is the reason it is not the easiest fit during a power cut. It works, but it asks more of the room. You need enough light to place ships properly and enough care when passing the device so nobody glimpses the board. If the room is very dark, that gets fiddly.
On the other hand, if the phone has enough charge and you want a more involved head-to-head, Salvo is the one that feels least samey over multiple rounds. The hidden boards give it more suspense than the other two. It can be a good choice if the outage is dragging on and both players want something beyond quick rounds.
The practical advice is simple. Use Salvo if you have a bit of battery, a bit of light, and players who can pass the phone without conducting a fraud inquiry after every turn. If not, start with Connect Four.
What to do first, while you still have a connection
If the power is flickering or you know weather is about to do something irritating, open the games while you still have internet. After one online visit, they are stored on the device and can be played with no signal.
For this situation, the sensible order is:
- Open Connect Four.
- Open Dots & Boxes.
- Open Salvo.
- Then switch the phone to airplane mode if you are trying to conserve battery.
You do not need an account to play. A parent can optionally sign in to sync scores across devices, but nobody has to. For a power cut, the simpler route is usually best. Open the game, hand over the phone, and carry on.
It also helps to turn the brightness down a bit before the battery becomes an issue. That is not a feature of GameJar, just ordinary self-preservation.
If you are trying to decide which game to preload first, make it Connect Four. It is the easiest to explain, quickest to start, and best suited to a no-router, low-battery evening. For a related case, Connect Four In the Car | GameJar makes many of the same points, minus the candles.
The short version
During a power cut, pass-and-play games on one phone can work well because they need no extra kit, no signal, and no setup once loaded. But the battery is the boss, so the best game is usually the one that gives you short rounds and little fuss.
In this category, Connect Four is the strongest all-round choice. Dots & Boxes is steady and calm, but can run longer. Salvo is more involved, though it is a bit less convenient in a dark room because of the hidden boards.
That is the useful thing about GameJar here. It is not trying to turn a blackout into a lifestyle. It just gives you a few solid options that work when the router does not.
FAQ
Do these two-player games on one phone need Wi-Fi during a power cut?
No. After one online visit, the games are stored on the device and work with no signal. That is the part worth doing before the connection disappears.
Which game is best if the phone battery is low?
Connect Four is the best bet. Rounds are short, turns are quick, and it is easy to stop after one game instead of drifting into a long session.
Are these really pass-and-play, or does each person need their own device?
They are pass-and-play. Two players use the same phone or tablet. There is no online multiplayer, no chat, and no separate device needed for the second player.
Is Salvo awkward in the dark?
It can be. Because each player hides ships on their own board, you need to pass the device carefully and avoid showing the screen. It still works, but it is less straightforward than Connect Four or Dots & Boxes when the lights are out.
Do we need to create an account before playing?
No. No account is needed to play any of the games. A parent can optionally sign in to sync scores across devices, but for a power cut that is not necessary.
