Liar's Dice

Liar's Dice is a dice game where each player is given five dice and cup to roll and hide them with. Players make successively higher declarations regarding the results of all the dice remaining in the game, e.g. "there are ten sixes". However, someone can always contest the bid. When that happens, all the dice are revealed and either the bidder or the caller loses dice, depending on who was correct. The last player with dice is the winner.

As a public domain dice game there are a number of variants or similar games called Liar's Dice. This includes one that is often played with Poker Dice, and differs from the marketed versions in that players only declare on their own hand's value (as opposed to all dice being in play), using poker-hand values.

String Railway

String Railway is a unique train game that consists of colored strings, tokens, station tiles, and a board for scoring. To set up, first place the string tied in a big circle on the table to establish the field area for the game. Next, place a small circle of string to represent mountains and a line of string to represent a river. Finally, place the main stations for each player equal distances apart from one another.

On a turn, you draw and place a station tile, then try to place a railroad string between your stations in an effort to connect them in order to form your own train network. Connected stations earn victory points (VPs).

After five turns, the game ends and the player with the most VPs wins.

Grimoire

Grimoire is the French word for "spellbook", and smart use of your spellbook – more specifically, the spells within said book – will determine whether you succeed in this game.

Each turn in Grimoire starts by revealing several cards on the game board; each card has either a victory point (VP) value or is a character with a particular way to earn VPs at the end of the game. Once these cards are revealed, each player secretly chooses which spell to cast in his spellbook by placing a bookmark on the appropriate page. Everyone then reveals which spell they chose, with the spells going off in order from weakest (those with the lowest numbers) to strongest. Some weak spells nerf stronger ones, and the order in which players choose cards from the display can be flipped topsy-turvy depending on who plays which spells.

In the One Draw and Z-Man versions, the game ends as soon as one player has collected either ten character cards or ten treasure cards; in the Schmidt Spiele version, the game ends after a fixed number of rounds. All players then tally their points, and the player with the highest score wins.

Differences between the versions:

As noted above, the game ending conditions differ in the 2012 Schmidt Spiele version.
The Z-Man Games and Schmidt Spiele versions of Grimoire accommodate five players, while the original One Draw release allows only 2-4 players.
The Schmidt Spiele version contains four new character cards and two new treasure cards, includes hardcover books instead of softcover, changes two spells, and uses a more elaborate game board that depicts the spells and allows players to mark the spells chosen with small figures to track who has played what.

Karuba

This is a tile-laying race game with players starting with boards that are identical, and one player drawing tiles that they all will use. They race to get their explorers to temples first and earn points. Along the way they can collect additional points by collecting items off the paths they create.

Description from the English Ruleset:

Many moons have come and gone since your boats departed on the journey to Karuba. Once you arrive on the island, each player will lead an expedition team of four adventurers. Now you just have to navigate your way through the dense jungle to make it to the temples. „Just“ may be something of an understatement; the ancient jungle trails have to be found and uncovered first! Hurry up and be the first to reach the temples to collect the most valuable treasures. Many paths have dead ends and you need to be patient to find the right/best way (through the jungle). Look! A gold nugget! You can pick it up and collect it, same applies to the shiny crystals along the paths.
