Hex War
Land a piece and every enemy beside it turns yours. Hold the most hexes to win.
Two colours and a board of hexagons. On your turn you pick one of your pieces and choose a cell within two of it. Next door and your piece is copied — you keep the one you had and gain another. Two away and it moves there instead, leaving its old cell empty. Either way, every enemy piece touching the cell you land on turns your colour.
That is the whole game. The board fills up, and whoever holds more of it takes the round.
Pass the phone to the person next to you, or play the computer at Easy, Medium or Hard. Easy grabs what it can see; Hard guards its edges and punishes a loose piece. The sides take turns opening a round, so it is worth playing both.
Nine boards. Standard and Small are plain hexagons; the other seven take cells out — Pillar, Windows, Ring, Wide ring, Star, Narrows and Islands — and every hole changes what you can reach and what you can hold. Islands leaves patches you have to jump between. Narrows leaves a strip down the middle that neither side can walk to.
Ten piece colours and six board surfaces. Tap a player's card to change their name and their colour, and taking the colour the other player is using swaps the two of you rather than refusing. The whole page washes toward whoever is to move, so whose turn it is is something you see rather than something you read.
No ads, nothing to buy, and no account. The app asks for nothing but the permission that lets it buzz when a piece lands, and it has no internet access at all.
