• Rounds: 13 turns per player
• Objective: Highest total score wins

• Rolls: Up to 3 rolls per turn with keepable dice

• Click CREATE GAME, choose token and bet within configured limits.
• Select 2–4 players; optionally invite addresses for a private game.
• The lobby auto-starts when full; start order is randomly assigned on-chain.
• There is a limited join window; expired lobbies cannot be joined.

• Each turn consists of up to 3 rolls.
• First roll: Roll all 5 dice.
• If you achieve the combo you want, you may score immediately.
• Second roll: Set aside any keepers and re-roll the rest (or re-roll all).
• If you achieve the combo you want, you may score now.
• Third and final roll: Roll any number of dice, including previous keepers.
• You must enter a score this turn in exactly one empty box, even if it’s 0.

• Each turn, you must fill exactly one empty box on your scorecard.
• You can complete boxes in any order across upper or lower sections.
• If no valid scoring option fits, you must enter a 0 in one empty box.
• Once a box is filled, it cannot be used again.
• Summary of scoring is printed on the scorecard.

• Aces (1s), Twos (2s), Threes (3s), Fours (4s), Fives (5s), Sixes (6s).
• Score = sum of dice showing that face value.
• Example: 3 Threes = 9 points in Threes box.
• Example: 2 Aces = 2 points in Aces box.
• Upper Section Bonus: If your total in the upper section exceeds 63 points, add 35 points.
• Tip: Rolling three of each number (3x1 + 3×2 + … + 3×6 = 63) reaches the threshold.

• Three of a Kind: Total of all 5 dice. Requires at least 3 dice showing the same number.
• Four of a Kind: Total of all 5 dice. Requires at least 4 dice showing the same number.
• Full House: Set score 25 points. Any 3 of a kind + any pair.
• Small Straight: Set score 30 points. Any 4 consecutive values (e.g., 1-2-3-4, 2-3-4-5, 3-4-5-6).
• Large Straight: Set score 40 points. Any 5 consecutive values (1-2-3-4-5 or 2-3-4-5-6).
• Chance: Total of all 5 dice. No combo required.
• Yahtzee: Set score 50 points. Five of a kind.

After you have scored Yahtzee (50) positively, each additional Yahtzee in later turns grants a 100‑point bonus. Placement follows the Joker rule enforced on-chain:

• If the matching upper box (same face value) is empty, you must score the sum of the five dice there.
• Otherwise, you may score in one of these lower categories: Three of a Kind, Four of a Kind, Full House, Small Straight, Large Straight, or Chance (using the normal scoring for that category).

Important: If you have already scored 0 in the Yahtzee box, the 100‑point bonus is not available.

• After all players complete 13 turns, sum the upper and lower sections, add any bonuses.
• The highest Grand Total wins.
• Don’t forget to add the 35-point upper section bonus if your upper total exceeds 63.

• Choose which box to fill each turn; some combos are easier to roll than others.
• You may need to enter a 0—plan which box is least valuable to sacrifice.
• Balance scoring between upper and lower sections to maximize total.
• Save Chance for later when options are limited.
• Success isn’t just high rolling; it’s choosing the right box at the right time.

• Large Straight qualifies as Small Straight if you choose to score it there.
• Use Chance when no other valid option fits and you must avoid a 0.
