Tock is a board game, similar to Pachisi, Ludo, Aggravation, "Jeu des petits chevaux" or Sorry!, in which players race their four tokens (or marbles) around the game board from start to finish—the objective being to be the first to take all of one's tokens "home". At the beginning of each round players are dealt 5 cards which they play in turns to move their tokens (or marbles) around the board. If at any time a token lands exactly on the field occupied by another token then the moved token replaces the resting one (which is placed back into the corresponding player's starting area). If a player on his turn has no cards he can play with his tokens (or which he can't play against the other players, like a 5 or 10 in some variations) then he must discard his entire remaining hand and wait for the next hand to be dealt.
A starter is a card that allows a player to move a new token to the starting field. Aces and Kings are starters.
A token at the starting field is immune to capture or swapping by an opponent, and additionally it creates a blockade. No players can pass a token that is on its starting field, either forward or backwards (with a 4).
To end the game, you need the exact count of fields to make it into the Home, and you need to fill the home from the top down. Tokens are not allowed to jump over other tokens within the home field.
- Aces: +1 or starter. - Fours: -4. - Fives: +5 to token owned by another player. - Sevens: 7 times +1 which can be split among all tokens. - Tens: +10 or force a player to discard a card randomly. - Jacks: +11 or swap two tokens. - Kings: +13 or starter.
Aside from a "Free for all" play style the game also supports a Two vs. Two vs. Two (2v2v2) players, where Players on opposite sides of the board team up.
