HOW TO PLAY
Yamio is a Yam / Yahtzee-style dice game. Roll five dice, hold the ones you like,
and pick a category to score. Fill all 13 categories — biggest total wins.
1 · Your Turn
Tap ROLL to throw all five dice.
Tap HOLD under a dice to lock it for the next roll.
You get up to 3 rolls per turn. You can stop early any time.
When you're done rolling, pick a category in your scorecard to bank the score.
2 · Scoring Categories
Category
How to Score
Ones – Sixes
Sum of dice matching that number
3 of a Kind
3+ matching dice → sum of all 5 dice
4 of a Kind
4+ matching dice → sum of all 5 dice
Full House
3 of one + 2 of another → 25
Small Straight
4 in a row → 30
Large Straight
5 in a row → 40
YAM!
All 5 dice the same → 30
Chance
Any combo → sum of all 5 dice
Upper Bonus: score 63+ in the Ones–Sixes section to earn a
+35 bonus. The Upper Bonus Helper shows how many of each number
you still need.
3 · End of Game
Each category can only be used once.
If a category doesn't fit, you can scratch it for 0 points.
Game ends when all 13 categories are filled. Highest total wins.
4 · Power-Up Mode OPTIONAL
Power-Up Mode is a fun alternate mode for vs Bot and multiplayer.
Pick it from the mode selector in the bot/match menu or the waiting room.
Start: choose 1 power-up before the first roll.
Earn more by rolling a YAM (5-of-a-kind) or reaching the +35 upper bonus.
Tap a power-up in your power-up bar to activate it. Some ask you to tap a dice.
Each power-up can only be used once per copy.
Extra Roll
Get one bonus reroll this turn
Freeze Dice
Lock one dice — carries to your next turn
Double Points
Double the score for your next category
Lucky Dice
Reroll one dice — higher chance of 5 or 6
Undo Move
Take back your last score choice
Chance Roll
Reroll ALL dice — next positive score doubles, no more rolls this turn
Yam or Strike
First roll only: forces 4×1s + 2 rerolls on the last dice — YAM or strike YAM!
5 · Mega Yam Mode OPTIONAL
Mega Yam is an alternate scoring mode for vs Bot and multiplayer.
Pick it from the mode selector in the bot menu or the multiplayer
waiting room. Standard rules apply — but rolling more than one YAM
really pays off.
Uses real Yahtzee scoring: YAM 50, Small Straight 30, Large Straight 40, upper bonus +35 (the rest is unchanged).
Score your first YAM (5-of-a-kind) in the YAM! box as usual.
Every extra YAM you roll after that earns a +100 Mega Yam bonus.
The YAM! box is already used, so you must strike the extra YAM into another open category (it scores there too — e.g. five 4s in Fours, or as a Full House).
No bonus if your YAM! box was struck for 0 — you have to bank a real YAM first.
6 · Tips
Tap PREDICT after a roll for AI-suggested holds and best scores.
In multiplayer, tap an opponent's name to peek at their scorecard.
Save big categories (YAM, Large Straight) for when you actually roll them — scratch a low Ones early if you must.
Watch the Upper Bonus tracker — that +35 often decides the game.
