How to start
- Open bigboard.games on every device and tap Start a table on one of them.
- The others join by themselves on the same Wi-Fi; elsewhere, scan the QR code or type the four-letter code.
- Lay the devices edge to edge, screens up, as the drawing shows, and pick the game.
A ring of four screens
Push four devices together in a 2 × 2 block, one player at each. The block closes a ring, so the road leaves the first screen by one side, rounds each of the other three once and comes back by its other side to the lantern. Laid in a row instead, it runs out to the last screen and loops back, crossing every seam twice.
Phones and tablets mix freely. With any phone at the table, cells are 12.5 mm across; four tablets play 15 mm cells. You don't need four devices for four people: two can share a device, each with a ground from their own edge, so two tablets seat the whole table.
Four grounds against bigger waves
Each player's ground grows from their seat and covers an equal share of the road. Four players bring more of every bug, packed closer, and from wave 6 they come at full four-player strength, so the ground nearest the gate can't hold the middle waves alone: everyone builds where the road reaches them, and the table levels up together.
Gates can be One per player: four gates, each a branch from the table's edge into the main road, every wave split between them. The boss always takes the first gate, on the last wave of 15, or on waves 10, 20 and 30 of a long match. With one fewer, 3 player tower defense plays a row of three.
Bots, friends far away and drops
Short of a fourth? Add a bot as you arrange the table: it builds on its own ground with its own gold. A friend far away joins by link and plays their ground from a view of the whole field, their seat at the bottom.
If a device drops, every screen pauses and its seat waits 10 minutes for it to come back to the match as it was. Among the party games for phones it is the one where the whole table plays on the same side, and the other 4 player games seat a table the same way.
4 players: questions and answers
Can four play on two tablets?
Yes, two to a tablet, each with a ground from their own edge.
Can each player have their own gate?
Yes, pick One per player in Gates: four gates, each wave split between them.
Are the waves harder with four?
Yes, more bugs, closer together, at full strength from wave 6, while a wave lasts as long.
Does a dropped device end the match?
No, the match pauses and holds its seat for 10 minutes; only if nobody comes back does it end.
