## What is Five?

Five-O puts a numerical twist on the classic crossword board game!

Instead of letters, you place number tiles, forming sequences that must add up to multiples of five, with no more than five tiles per sequence. Think strategically, maximize your bonuses, and outscore your opponent!

Features:

Easy to learn rules  
Single player mode with challenging computer opponents
Online Multiplayer! Play with your friends or let Game Center find you a match
Simple controls, just touch and drag the tiles to the board 
Hints for when you get stuck

How to play: 

Players take turns placing intersecting sequences of numbers on the board which sum to multiples of five. For example, 7-3-8-7 would be a valid sequence because it adds up to 25. The sequence 3-9-5 is not valid because it adds up to 17 which is not a multiple of five. 

On each turn, players may play tiles in one straight line sequence, horizontally or vertically. The first sequence must be played on the center square, and all sequences after that must intersect with tiles already in play.

The score for each play is the sum of all the number tiles in sequences completed on that turn. Colored bonus squares award extra points and multipliers.

At the end of each turn, players draw new tiles to replace the ones played. The game ends when a player plays all of their remaining tiles and there are no more tiles left to draw.

### 5/5 — Pretty good, too much long ads

*2026-01-31, version 2.10.1*

Too long adds

### 5/5 — Läuft

### 5/5 — Love it

*2025-08-03, version 2.10.1*

Fab game, so very enjoyable.

### 5/5 — Brain power

*2025-02-17*

Absolutely love the game. It’s a great brain game. Taught my co worker how to play, will be showing more people this game.

### 4/5 — Medium vs Hard?

*2024-12-06*

Love the game but the difference between medium and hard levels is far too vast. Shouldn’t on one hand be able to win by 300 easily and on the other never get close.

### 5/5 — Worth the Download

*2021-05-03*

Game is relaxing, with enough levels to make it challenging.  Ads are there, but unobtrusive -  always a giant plus for me!

### 4/5 — Enjoy the game

*2020-11-12*

I really enjoy playing. I do wish that there were forfeit rules if players do not respond within 24 hours when it is there turn.  I don’t like waiting and wondering.  

Also, I wish there was a way to communicate with the other player.

### 1/5 — Screwed

*2020-01-13*

Played this game forever, now it no longer works. Doesn’t work with people I’ve played with for over a year, or anything to do with on-line gaming. Also, full of adds for other games now.  No longer a game worth playing!!!

### 1/5 — Trouble 🤨

*2019-11-08*

How am I able to play Five-O on my iPhone 11? The game doesn’t respond to my touch. I’m able to open the app. But no features of your app open up. Is there an update?
I really like the game but, I miss it.

### 1/5 — Cheater!

*2019-09-12*

This games does not add or multiply correctly; terrible game.
